Description

Thermoplastic resin composition

The present invention relates to a thermoplastic resin composition. More specifically, the present invention relates to (A) thermoplastic resin and (B) thermoplastic resin (A), wherein the mixing is carried out at a temperature in the range of 25 to 300 ° C., and the non-polymerizable liquid substance (B) remains in a liquid state. Prepared as a additive by mixing at least one nonpolymerizable liquid substance in a liquid state at a temperature in the range of 25 to 300 ° C., thereby dissolving or swelling the thermoplastic resin (A) in the nonpolymerizable liquid substance (B) It is related with the resin composition substantially the same as what becomes. The resin composition of the present invention, unlike the conventional resin composition prepared by melt extrusion method, during the preparation of the resin fired material, the thermoplastic resin (A), which is a component of the resin composition, and each of the nonpolymerizable liquid materials as additives do not experience high temperature conditions. It does not suffer from thermal degradation. Therefore, by molding the resin composition of the present invention, a molded article having excellent appearance, light resistance and mechanical properties can be obtained. The resin composition of this invention can be advantageously used as a molding material for manufacture of various molded objects, such as components for OA machines, components for home appliances, and electrical and electronic components. Moreover, especially when the resin composition of the present invention, in which the masterbatch is added to the same or different resin material as the thermoplastic resin used in the resin composition, is used as a masterbatch for producing molding materials, a great advantage arises. The molding material obtained by adding the resin composition of the present invention as a masterbatch to the resin material not only has improved melt molding ability, but also has a good appearance, excellent appearance, utilizing the fact that the resin in the masterbatch does not experience high temperature conditions. It has the advantage that a molded article having light stability and excellent mechanical properties can be easily produced from the molding material. In addition, in the production of the masterbatch made of the resin composition of the present invention, the excess liquid additive can be easily incorporated into the masterbatch without lowering the productivity of the masterbatch.

Molded bodies produced by molding thermoplastic resins such as polyphenylene ether resins have good heat resistance and good impact resistance. Therefore, thermoplastic resins are widely used as molding materials for the production of various molded articles, such as automobile parts, parts for home appliances, and OA machine parts.

Recently, in order to improve the properties of thermoplastic resins, various additives have been used in thermoplastic resins. For example, in order to improve the processability of the thermoplastic resin, attempts have been made to add liquid paraffin (mineral oil) to the thermoplastic resin. In addition, in order to impart flame retardancy to the thermoplastic resin, it has been attempted to add a liquid organophosphorus compound to the thermoplastic resin. The addition of the liquid additive to the thermoplastic resin is usually carried out using a melt extrusion method. However, when the addition of a liquid additive to a thermoplastic resin having a high melting temperature or a high glass transition temperature is carried out by melt extrusion, not only is a special supply equipment necessary for supplying the liquid additive, but also the handling of the liquid additive is complicated ( Iii) Problems arise. In addition, when melt-mixing a low-viscosity liquid additive and a high-viscosity thermoplastic resin together, the large viscosity difference between them differs from that of the liquid additive in the extrusion amount, so that the extrusion operation is unstable, and the high-viscosity thermoplastic resin during melt extrusion The problem arises that part of the remains unmelted, resulting in a final molded article with poor appearance and degraded mechanical properties.

In order to solve the problem caused by the large viscosity difference between the high viscosity thermoplastic resin and the liquid additive, a method of further melt mixing the resin material obtained by melt mixing of the polystyrene resin and the polyphenylene ether resin with the liquid additive for the polymer. (See Japanese Patent No. 2612396 and Japanese Patent Laid-Open No. 5-295249). The technique has made it possible to reduce the incidence of problems in which some of the high viscosity resin, polyphenylene ether resin, remains unmelted during melt extrusion. However, in the above technique, when the polyphenylene ether resin and the polystyrene resin are melted at a high temperature, there arises a problem that the resin suffers from a noticeable discoloration, a decrease in light stability, and a decrease in mechanical properties due to breakage of the molecular chain.

In order to solve the problem, various proposals have been made. Examples of the above proposals include a method of using a resin composition consisting of a thermoplastic resin and an oil-containing resin obtained by impregnating a liquid oil in a porous, styrene-divinyl benzene copolymer (Japanese Patent Publication No. 7-122024); Prevention of the occurrence of bleeding-out of the additive from the molding material during molding, comprising using as a molding material a resin composition composed of a thermoplastic resin and a resin additive made by impregnating a liquid additive into the oil-absorbing crosslinked polymer. Method (Japanese Laid-Open Patent Publication 5-214114); A method in which a molded article having a matte appearance can be obtained using a resin composition obtained by incorporating a specific polymer into a thermoplastic resin as a molding material (Japanese Patent Laid-Open No. 6-57007); A method in which a molded article having improved impact resistance can be obtained using a resin composition obtained by incorporating a specific polymer into a thermoplastic resin as a molding material (Japanese Patent Laid-Open No. 6-73190); A method of using a powdery flame retardant for polymers obtained by impregnating phosphorus-containing flame retardant with amorphous silica (Japanese Patent Laid-Open No. 7-331244); A method of using an additive for a polymer, wherein the additive contains an inorganic carrier and a phosphorus-containing flame retardant supported thereon (Japanese Patent No. 2588331); A method of using a resin composition obtained by gelling a liquid additive with a gelling agent to obtain a solidified liquid additive and mixing the solidified liquid additive into a synthetic resin (Japanese Patent Office 56-42619); A method of using a resin composition obtained by dissolving a phosphate compound in a solvent to obtain a solution and dispersing the solution in polypropylene by melt kneading (Japanese Patent Laid-Open No. 4-1233); And a method of using a masterbatch composed of an oil absorbent polymer and an additive for a polymer (Japanese Patent Laid-Open No. 9-52956). Each of the above techniques aims at improving the handleability of the liquid additive which absorbs or adsorbs the liquid additive to the oil absorbent resin to reduce the appearance amount of the liquid additive. Therefore, in the resin composition obtained by any of the above techniques, the oil-absorbent resin in which the liquid additive is absorbed or adsorbed is in a powder or non-powder solid state, so that when the resin composition is melt-molded using an extruder, improved appearance and excellent mechanical A molded article having the properties can be obtained.

It is known to use a resin composition obtained by dissolving or impregnating a thermoplastic resin in a polymerizable monomer or crosslinkable compound and then polymerizing the polymerizable monomer or crosslinkable compound. Examples of the above technique are methods of using a resin composition prepared by impregnating polyvinyl chloride with an aromatic vinyl monomer and then polymerizing the aromatic vinyl monomer (JP-A-61-40702 and 62-1972, and JP-A-3). 197521); A method of using a resin composition prepared by dissolving a polyphenylene ether resin and a rubber polymer in an aromatic vinyl monomer and then polymerizing the aromatic vinyl monomer (European Patent No. 226149 and Japanese Patent Laid-Open No. 7-242791); A method of using a polyphenylene ether resin solution containing an aromatic vinyl monomer to form a coating or film (Russian Patent No. 2069674); A method for producing a thermosetting laminate using a polyphenylene ether resin, a liquid epoxy compound, a flame retardant, and a curing catalyst as an electric component in which they are mixed with each other and the resulting mixture is reacted by heating at high temperature (Japanese Patent Laid-Open No. 7-3053); A method of using a polyphenylene oxide composition composed of a polyphenylene ether resin, a crosslinkable flame retardant and an initiator (Japanese Patent Laid-Open No. 62-148564). In each of the above examples, a mixture of an additive and a resin solution is provided and the mixture is polymerized or otherwise reacted. In this method, it is relatively easy to obtain a composition in which the resin and the liquid additive are uniformly mixed with each other. However, the above method has a disadvantage in that the polymerizable monomer is easily grafted to the thermoplastic resin, or the thermoplastic resin is easily crosslinked, and the characteristics inherent in the thermoplastic resin change.

In addition, Japanese Patent Laid-Open No. 50-50 describes a method for producing a molded article using a resin composition prepared by dissolving polyamide and phosphate in formic acid as a solvent. However, in the above method, after removal of the solvent from the resin composition, the polyamide and the phosphate are not uniformly mixed, so that it is impossible to obtain a resin composition exhibiting excellent appearance and excellent light stability. Other examples of known techniques are methods for producing a porous polymer structure, in which a polymer, such as a polyphenylene ether resin, is dissolved in diphenyl sulfone as a solvent and the resulting solution is contacted with a mixed solvent of acetone and methanol (Japanese Patent Laid-Open No. 8-24582). ); A process for producing a polyphenylene ether-containing molding material, in which a polyphenylene ether resin and another polymer are dissolved in a solvent to obtain a solution, and the solvent is removed from the solution in multiple steps (Japanese Patent Laid-Open No. 58-34829); And a method for producing fibers from a solution obtained by dissolving polyacrylonitrile in a solvent consisting of a solution of rhodanate (Japanese Patent Laid-Open No. 50-20029). However, in the above known technique, no additives for polymers are used to obtain a resin composition in which the resin and liquid additives are uniformly mixed with each other. In addition, a method of lowering the melting temperature of a polyphenylene ether resin, in which a plasticizer is dissolved in a solvent to obtain a solution, and the obtained solution is used for treating the polyphenylene ether resin is known (Japanese Patent Laid-Open No. 52-90596). ). However, in the above method, since the polyphenylene ether resin is not dissolved in the solution, it is impossible to obtain a resin composition usable for producing a molded article having good appearance, good light stability and good mechanical properties.

In addition, it is known to use resin compositions prepared by the process of dissolving resins such as polyphenylene ether resins in additives used for surface modification of polymers. For example, it is known to use an antistatic resin composition prepared from a solution obtained by dissolving a thermoplastic resin such as polyphenylene ether or polypropylene in an amine antistatic agent (Japanese Patent Laid-Open No. 50-105293 and U.S. Pat. 4,210,556, 4,314,040 and 4,147,742). As another example of the above technique, a method is known in which both a lubricating oil and a synthetic resin are dissolved in a solvent to obtain a solution and the solvent is removed from the solution to obtain a resin composition in which the lubricating oil is uniformly distributed in the synthetic resin (Japanese Patent Publication). 51-34536). However, additives (ie, antistatic agents and lubricants) used in the art are aimed at modifying the surface properties of the shaped bodies. Therefore, in the above technique, it is important that the additive is mainly present on the surface portion of the molded body. For this purpose, it is necessary that the additive has a moderately low compatibility with the resin. Therefore, when a resin composition having a high content of additives is intended to be produced by the above technique, it is necessary to melt-knead the resin and the additive at a high temperature, which inevitably degrades the resin and the additive. Therefore, it is impossible to mold the resin composition prepared by the above technique to obtain a molded article having excellent appearance, excellent light stability and excellent mechanical properties.

In this situation, the present inventor has made extensive and intensive studies to develop a resin composition which can be advantageously used for the production of various molded articles having the above problems and excellent appearance, excellent light stability and excellent mechanical properties. As a result, there is no problem that the resin composition produced by a specific method as described later is parallel to the resin composition prepared by the conventional melt extrusion method, such as thermal deterioration of the resin contained in the resin composition, and therefore the appearance of the resin composition of the present invention It has been found that it can advantageously be used for the production of molded articles which are much improved in terms of light stability and mechanical properties. A specific method according to the invention is an additive for (A) thermoplastic resin and (B) thermoplastic resin (A), wherein mixing is carried out at a temperature in the range of 25 to 300 ° C., and the non-polymerizable liquid substance (B) remains in a liquid state. As a mixture of at least one nonpolymerizable liquid substance in a liquid state at a temperature in the range from 25 to 300 ° C., and dissolving or swelling the thermoplastic resin (A) in the nonpolymerizable liquid substance (B). The addition of a masterbatch to a resin that is the same as or different from the resin used in the resin composition produces particularly great advantages when using the resin composition of the invention as a masterbatch for materials of molding materials. In other words, the molding material obtained by adding the resin composition of the present invention as a masterbatch to the resin material not only has improved melt molding ability, but also that the resin in the masterbatch does not experience high temperature conditions. It has the advantage that an improved molded body can be produced from the molding material in terms of properties. Further, in the preparation of the masterbatch composed of the resin composition of the present invention, it has been found that an excess of liquid additive can be easily incorporated into the masterbatch without lowering the productivity of the masterbatch. The present invention has been completed based on the novel finding.

Accordingly, a first object of the present invention is to provide a resin composition which can be advantageously used for the production of a molded article having good appearance, excellent light stability and excellent mechanical properties.

It is still another object of the present invention to provide a masterbatch which can easily impart excellent characteristics of the above object to a molded article prepared from the molding material obtained by adding the masterbatch to a resin material.

In one aspect of the invention, (A) a thermoplastic resin; (B) at least one nonpolymerizable liquid substance as an additive for the thermoplastic resin (A); And optionally (C) a resin composition consisting of a crystalline or amorphous solid material as an additive for the thermoplastic resin (A).

In the composition of the present invention, the thermoplastic resin (A) acts as a resin component, and each of the nonpolymerizable liquid material (B) and the solid material (C) has a desired property such as flame retardancy and fluidity in the thermoplastic resin (A). Grant.

In the resin composition of the present invention, the thermoplastic resin (A) is dissolved or swelled in at least one nonpolymerizable liquid substance (B). The resin composition of the present invention is prepared, for example, in the form of pellets (for example cylindrical pellets or spherical pellets) having a diameter of 0.01 to 10 mm. The pellet may be extruded to obtain a sheet or injection molded to obtain a molded body of a desired mold. In addition, as detailed below, it is particularly advantageous to use the resin composition of the present invention as a masterbatch for the production of molding materials, wherein the masterbatch is applied to the same or different resin material as the thermoplastic resin (A) used in the resin composition. Add.

The resin composition of the present invention can be produced without the need for the step of molding the thermoplastic resin (A) to keep the resin in a molten state. “Melted state” refers to the state of a thermoplastic resin having a temperature above the softening point of the thermoplastic resin, where the resin is melted and fluid. Usually, melt processing is performed in manufacture of the conventional (resin / additive) composition or conventional molded resin body used as a molding material. Regarding the temperatures conventionally used in melt processing (these temperatures are often referred to as simplifying later as "traditional melt processing temperatures"):

(1) for the preparation of a resin composition containing an amorphous polymer or for the production of a molded resin body using an amorphous polymer, conventional melt processing temperatures are above about 50 to 100 ° C. higher than the glass transition temperature (Tg) of the polymer;

(2) In the case of production of the resin composition containing the crystalline polymer or production of the molded resin body using the crystalline polymer, the conventional melt processing temperature is higher than about 50 to 100 ° C higher than the melting temperature (Tm) of the polymer.

When the polymer is in the molten state, the high temperature of the polymer in the molten state not only causes the cleavage of the polymer chain, but also causes side reactions, such as dislocation reactions, of the polymer chain (which are present in adjacent positions), which worsens the polymer. Therefore, in order to avoid the above disadvantages and to obtain a molded resin body having excellent appearance, light stability and mechanical properties, it is very important to give a thermoplastic resin used as a molding material having satisfactory fluidity at the lowest possible temperature. Therefore, it is preferable to carry out the production of the resin additive composition or the molded resin body used as the molding material at a temperature below the conventional melt processing temperature. Specifically,

In the case of the production of a resin composition containing an amorphous polymer or the production of a molded resin body using an amorphous polymer, the production method is within the range of 50 to 100 ° C. or lower than the conventional melt processing temperature and higher than the glass transition temperature (Tg) of the polymer. Performing at a temperature selected, most preferably at a temperature no greater than 90 ° C. above the Tg of the polymer (ie, preparation temperature ≦ Tg + 90 ° C.); And

In the case of production of a resin composition containing a crystalline polymer or production of a molded resin body using the crystalline polymer, the production method is in the range of 50 to 100 ° C. or lower than the conventional melt processing temperature and higher than the melt temperature (Tm) of the polymer. It is preferable to carry out at a temperature selected in the above, most preferably at a temperature of 90 ° C. or less higher than the Tg of the polymer (ie production temperature ≦ Tm + 90 ° C.).

In the resin composition of the present invention, the preparation of the resin composition can be carried out at a temperature lower than the conventional melt processing temperature using a method consisting of the mixing steps of (A) and (B):

(A) a thermoplastic resin, and

(B) at least one nonpolymerizable liquid substance as an additive to the thermoplastic resin (A),

Wherein the nonpolymerizable liquid substance (B) is in a liquid state at a temperature in the range from 25 to 300 ° C, preferably from 100 to 300 ° C, most preferably from 150 to 250 ° C

Mixing is carried out at a temperature in the range from 25 to 300 ° C., preferably from 100 to 300 ° C., most preferably from 150 to 250 ° C., in which the nonpolymerizable liquid substance (B) remains in a liquid state,

This dissolves or swells the thermoplastic resin (A) in at least one nonpolymerizable liquid substance (B).

Regarding the thermoplastic resin (A) and the nonpolymerizable liquid substance (B), when the nonpolymerizable liquid substance (B) is adsorbed or absorbed by the thermoplastic resin (A), the resin composition is a powder of a part of the thermoplastic resin (A). It exists in the form of a resin composition, and since the molded resin body manufactured from the said resin composition has a rough surface, and the mechanical property of the molded resin body manufactured from the said resin composition becomes low, it is disadvantageous. In the present invention, a mixture of the thermoplastic resin (A) and the nonpolymerizable liquid material (B) (the thermoplastic resin (A) is dissolved or swelled in at least one nonpolymerizable liquid material (B)) is continuously operated at a temperature within the above range. Or batchwise.

A resin composition of the present invention which dissolves or swells the thermoplastic resin (A) in at least one nonpolymerizable liquid material (B) and a resin composition which adsorbs or absorbs the nonpolymerizable liquid material (B) in the thermoplastic resin (A) (the The difference between the resin composition, which is often then simplified as the "adsorption / absorption composition") is described below.

In the case of the resin composition of the present invention, when the resin composition is placed in the container and the container is tilted, the resin composition flows along the inner surface of the container. On the other hand, in the case of the adsorption / absorption resin composition, the resin composition is in powder form or in the form of a solid mass. Therefore, when the resin composition is placed in the container and the container is tilted, the resin composition does not flow.

On the other hand, in the resin composition of the present invention, the non-polymerizable liquid material (B) dissolves the thermoplastic resin (A) in at least one non-polymerizable liquid material (B) at a mixing temperature selected within a range of 25 to 300 ° C. As long as it swells, the non-polymerizable liquid substance (B) may be in a state of being adsorbed or absorbed by the thermoplastic resin (A) at a temperature lower than the temperature at which mixing of the thermoplastic resin (A) and the non-polymerizable liquid substance (B) is performed. For example, the adsorption / absorption composition as a masterbatch using polyphenylene ether resin (PPE) as the thermoplastic resin (A), and a resin (which may be the same as or different from the polyphenylene ether resin used in the resin composition). When molding a molding material consisting of the material, the resulting molded product has a large number of undissolved melts of PPE that have not experienced melting, so that the appearance of the molded product is poor. Additionally, while the resin composition undergoes the molten state during molding, the resulting molten product has an adversely high yellowness (YI) and an amount greater than 0.5 mole, relative to 100 moles of repeating oxymethylene units of polyphenylene ether resin. It has a hydroxyl group. On the other hand, the resin composition of the present invention and the polyphenylene used in the resin composition as a masterbatch {dissolves or swells the polyphenylene ether resin as the thermoplastic resin (A) in the non-polymerizable liquid material (B)}. When molding a molding material made of a resin material (which may be the same as or different from an ether resin), it is possible to obtain a molded article having an excellent appearance without undergoing the above disadvantageous phenomenon. In the present invention, when the temperature at which the mixing of the thermoplastic resin (A) and the nonpolymerizable liquid substance (B) is performed exceeds 300 ° C, each of the thermoplastic resin (A) and the nonpolymerizable liquid substance (B) undergoes thermal degradation. It should be noted that the resulting resin composition has poor mechanical strength, light stability and color tone.

As already mentioned above, in the present invention, the nonpolymerizable liquid substance (B) as an additive to the thermoplastic resin (A) is a substance in a liquid state at a temperature in the range of 25 to 300 ° C. The nonpolymerizable liquid substance (B) acts to impart the desired properties to the thermoplastic resin (A). When the molded resin body is obtained using the resin composition of the present invention, most of the nonpolymerizable liquid substance (B) usually used in the production of the resin composition of the present invention remains in the obtained molded body. The non-polymerizable liquid substance (B) is not included in the non-polymerizable liquid substance (B) as defined in the present invention.

In the present invention, the nonpolymerizable liquid substance (B) preferably has compatibility with the nonpolymerizable liquid substance. In the present invention, compatibility is defined as follows. 50 parts by weight of the particulate thermoplastic resin (A) and 50 parts by weight of the non-polymerizable liquid substance (B) having an average particle diameter of 15 μm to 1 mm are mixed and then stirred at a temperature of 200 ° C. for 1 hour. The resulting mixture is filtered using a glass filter having a pore diameter of 120 μm while maintaining the temperature of the mixture at 200 ° C. The weight of the mixture remaining in the glass filter is then measured. The ratio of the weight of the component (A) / component (B) mixture remaining in the glass filter to the compatibility of the thermoplastic resin with the nonpolymerizable liquid material (B) to the weight of the thermoplastic resin in the resin composition before filtration (% of filtration) It is defined as). In the present invention, the filtration residual ratio is preferably 50% or less, more preferably 30% or less, even more preferably 10% or less.

In the present invention, it is not preferable to use the additive used in the surface modification of the thermoplastic resin (hereinafter often referred to simply as "surface modifier") as the non-polymeric liquid material (B), as the additive is defined above. This is because it is poor in compatibility. Specific reasons for the above are as follows. With respect to the surface modifiers, it is very important that the surface modifiers bleed during molding so that the surface modifiers are predominantly located in the surface portion of the resulting molded body so as to exert a surface modification effect. Therefore, surface modifiers are necessary to have low compatibility with the resin. In the case of obtaining the resin composition using the surface modifier, it is necessary to carry out hot melt processing, thereby deteriorating the resin and the additive. In addition, in order to obtain a resin composition containing a high content of the surface modifier, it is necessary to carry out melt processing, particularly at very high temperatures. Therefore, as defined above, it is not preferable to use surface modifiers as nonpolymerizable liquid substance (B). However, the surface modifiers can be used in conjunction with another nonpolymeric material (B) to avoid the above disadvantages associated with the use of surface modifiers. In this case, the compatibility between the thermoplastic resin (A) and the mixture of the surface modifier and the other nonpolymerizable liquid substance (B) is preferably used in the amount of 50% or less with respect to the filtration residual ratio. Specifically, the amount of surface modifier is preferably 30% by weight, more preferably 20% by weight or less, even more preferably 10% by weight or less, relative to the weight of the other nonpolymerizable liquid material (B).

On the other hand, the conventional additives used for improving the flame retardancy, fluidity and the like of the thermoplastic resin have satisfactorily high compatibility with the thermoplastic resin (A) and can dissolve the thermoplastic resin (A) at a relatively low temperature. Therefore, when the additive is used as the nonpolymerizable liquid substance (B), thermal degradation of the thermoplastic resin can be controlled. As another index for evaluating the compatibility of the nonpolymerizable material (B) with the thermoplastic resin (A), a solubility parameter SP can be mentioned. In the present invention, the difference between the SP value of the thermoplastic resin and the SP value of the non-polymerizable liquid substance (B) is preferably 3 or less, more preferably 2 or less, most preferably 1 or less.

In the present invention, the solid material (C) is a material which is a crystalline solid or an amorphous solid at a temperature of 300 ° C. or less. In the case of the nonpolymerizable liquid substance (B), the solid substance (C) functions to impart desired properties to the thermoplastic resin (A). The solid material (C) is used in an amount such that satisfactory compatibility between the non-polymeric material (B) and the thermoplastic resin (A) does not adversely affect.

In the present invention, the resin composition of the present invention is prepared using a solvent (D) capable of decomposing or swelling the thermoplastic resin (A) in order to improve the compatibility of the nonpolymerizable material (B) with the thermoplastic resin (A). . Specifically, in this case, the above-described mixing of the thermoplastic resin (A) and the non-polymerizable material (B) is carried out in the presence of the solvent (D) in the resin composition of the present invention, and after mixing, the solvent (D) is removed. It can manufacture. Regarding the solvent (D), 0.1 to 100 parts by weight, more preferably 1 to 50 parts by weight, and still more preferably 5 to 20 parts by weight of the solvent (D) are used relative to the thermoplastic resin (A). In order to achieve the desired compatibility of the non-polymeric material (B) and the thermoplastic resin (A), the difference in the SP value between the thermoplastic resin (A) and the solvent (D) and the SP between the non-polymerizable liquid (B) and the solvent (D), respectively The difference in teeth is 3 or less, more preferably 2 or less, even more preferably 1 or less. Furthermore, it is preferable that the solvent (D) has a boiling point that is higher than the temperature at which the mixing of the thermoplastic resin (A) and the nonpolymerizable liquid substance (B) is carried out to 300 ° C or lower.

In the present invention, it is preferable to perform mixing of the thermoplastic resin (A) and the nonpolymerizable liquid substance (B) in the absence of a polymerizable compound, such as a vinyl monomer. When mixing is carried out in the presence of a polymerizable compound, the compound is liable to be grafted onto the thermoplastic resin or to cause a crosslinking reaction, resulting in disadvantages such as changes in the intrinsic properties of the thermoplastic resin (A) or of the thermoplastic resin (A). It leads to a deterioration of the thermoplastic.

The resin composition of the present invention can be advantageously used as a masterbatch for producing a molding material for melt extrusion, wherein the masterbatch is added to a resin material which may be the same as or different from the thermoplastic resin (A) used in the resin composition. The molding materials can be advantageously used for the production of various shaped bodies, such as injection molded bodies (eg casings or internal parts for OA machines, household appliances, etc.), films, sheets and foams.

Hereinafter, the components of the composition of the present invention will be described in detail.

In this invention, it is preferable that a thermoplastic resin (A) shows high compatibility with a nonpolymerizable liquid substance (B). Examples of the thermoplastic resin (A) include polyphenylene ether resin, polystyrene resin, polyester resin, polyphenylene sulfide resin, polycarbonate resin, polyolefin resin, polyamide resin, polymethacrylate resin, polyacetal resin , Polyarylate resins, polysulfone resins, polyether imide resins, polyether sulfone resins, polyether ether ketones and the like. In the present invention, examples of the thermoplastic resin (A) also include a thermoplastic elastomer having the same polymer structure as that of any of the above thermoplastic resins.

Regarding the index for selecting a thermoplastic resin preferred as the thermoplastic resin (A), when the amorphous polymer is used as the thermoplastic resin (A), the glass transition temperature (Tg) can be used as the index, and the crystalline polymer is used as the thermoplastic resin (A). When used as), the melting temperature (Tm) can be used as an index. The glass transition temperature (Tg) of the amorphous polymer or the melting temperature (Tm) of the crystalline polymer is preferably at least 85 ° C, more preferably at least 100 ° C. When an amorphous polymer having a glass transition temperature (Tg) of less than 85 ° C or a crystalline polymer having a melting temperature (Tm) of less than 85 ° C is used as the thermoplastic resin (A), the advantages of the present invention in the conventional melt extrusion method The reason for not being large is that the thermoplastic resin having the very low glass transition temperature (Tg) or the very low melting temperature (Tm) can be melt processed or melt molded at a low temperature. On the other hand, when an amorphous polymer having a glass transition temperature (Tg) of 85 ° C. or higher or a crystalline polymer having a melting temperature (Tm) of 85 ° C. or higher is used as the thermoplastic resin (A), the conventional melt extrusion method This is notable because the thermoplastic resin having the very high glass transition temperature (Tg) or the very high melting temperature (Tm) can be melt processed or melt molded at a high temperature. That is, a resin composition containing a thermoplastic resin having a very high glass transition temperature (Tg) or a very high melting temperature (Tm) is subjected to a conventional melt extrusion method, and each thermoplastic resin and its additives inevitably undergo thermal degradation. Suffer. As mentioned above, in the present invention, there is no need for melt processing at a high temperature, and therefore there is no danger of thermal degradation.

Preferred examples of the thermoplastic resin (A) include polyphenylene ether resins, polystyrene resins and polycarbonate resins. Examples of polystyrene resins include rubber modified styrene polymers. A particularly preferred example of the thermoplastic resin (A) is a polymer mixture of a polyphenylene ether resin and a polystyrene resin, because it exhibits excellent solubility in the nonpolymerizable liquid substance (B).

It is preferable that the thermoplastic resin (A) used by this invention is resin which does not experience melt processing. For example, after completion of the preparation of the polyphenylene ether resin, the polyphenylene ether resin is obtained in the form of a solution or slurry containing the polyphenylene ether resin, not in a molten state. If the thermoplastic resin produced in the above non-melt state is used as the thermoplastic resin (A), before use, it does not experience melt processing in which the thermoplastic resin is brought into the molten state as defined above. On the other hand, after completion of the preparation of the polystyrene resin, the polystyrene resin is obtained in a molten state; The production method for producing the thermoplastic resin in the molten state is excluded from the category of melt processing mentioned herein.

Regarding the form of the thermoplastic resin (A) used in the present invention, there is no particular limitation. However, from the viewpoint of improving the solubility of the thermoplastic resin (A), the thermoplastic resin (A) is a powder having a number average particle diameter of 0.01 to 10,000 μm, more preferably 0.1 to 1,000 μm, still more preferably 1 to 100 μm. desirable. When the number average particle diameter of the thermoplastic resin (A) is less than 0.01 µm, aggregation of the thermoplastic resin particles is likely to occur, so that the handleability and the quality of the thermoplastic resin are deteriorated. On the other hand, when the number average particle diameter of the thermoplastic resin (A) is more than 10,000 µm, the dissolution rate of the thermoplastic resin (A) into the nonpolymerizable liquid substance (B) is lowered, so that a part of the thermoplastic resin particles (that is, Cosmetic melt of the resin) tends to remain intact in the resin composition, thereby lowering the appearance and mechanical properties of the final molded article.

In the present invention, polyphenylene ethers which can be used as thermoplastic resins (A), hereinafter often referred to simply as "PPE", are homopolymers and / or copolymers consisting of a plurality of polymer chains, each of which It consists of repeating oxyphenylene units represented by:

Of these, poly (2,6-dimethyl-1,4-phenylene ether) is preferred. The method for producing the PPE is not particularly limited. For example, PPE can be readily prepared by the method described in US Pat. No. 3,306,874 which oxidizes, for example, 2,6-xylenol using a complex of copper (I) salt and amine as catalyst. In addition, the PPE can also be easily produced by other methods described, for example, in US Pat. No. 3,306,875, US Pat. No. 3,257,357, US Pat. No. 3,257,358, Japanese Patent Office 52-17880, Japanese Patent Application No. 50-51197. . The reduced viscosity ηsp / c (measured at 0.5 g / dl of chloroform solution at 30 ° C.) of PPE used in the present invention is preferably in the range of 0.20 to 0.70 dl / g, more preferably 0.30 to 0.60 dl / g. As a method for achieving the above range of the reduced viscosity of the polyphenylene ether, a method of properly selecting the amount of the catalyst used in the preparation of the polyphenylene ether can be mentioned.

As one or more vinyl comonomers copolymerizable with aromatic vinyl monomers, unsaturated nitrile monomers such as acrylonitrile or methacrylonitrile can be used to obtain rubber modified styrene copolymers with good oil resistance. Moreover, in order to lower the melt viscosity of an aromatic vinyl monomer, the acrylate comonomer which has a C1-C8 alkyl group can be used. In addition, other comonomers such as α-methylstyrene, acrylic acid, methacrylic acid, maleic anhydride, N-substituted maleimide, and the like may be used to improve the heat resistance of the final resin composition.

When aromatic vinyl monomers are used in the form of monomer mixtures with comonomers, the amount of vinyl monomer copolymerizable with aromatic vinyl monomers in the monomer mixture is usually in the range of 0 to 40% by weight.

When the content of the rubber polymer and the comonomer in the rubber modified styrene polymer is within the above range, a good balance of impact resistance and rigidity can be achieved with respect to the final molded product. The diameter of the rubber particles in the rubber modified styrene polymer is preferably 0.1 to 5.0 μm, more preferably 0.2 to 3.0 μm. When the rubber particle diameter is in the above range, the impact resistance is particularly improved.

Regarding the rubber modified styrene polymer, the reduced viscosity ηsp / c (measured at 0.5 g / dl of the solution at 30 ° C.) of the solvent soluble material, which is a measure of the molecular weight, is preferably 0.30 to 0.80 dl / g, more preferably 0.40 to 0.60 dl / In the range of g, where toluene is used as the solvent when the styrene polymer is a polystyrene resin, methyl ethyl ketone is used as the solvent when the styrene polymer is an unsaturated nitrile / aromatic vinyl copolymer.

Among these, the para position is preferable. In the compound of the formula (4), it is preferable that the sum of the individual carbon numbers of the substituent alkyl groups is 12 to 30. Compared to the compound of the formula (4) having only one aromatic ring substituted with only one long chain alkyl group, each substituted with an alkyl group (its carbon number is smaller than that of the long chain alkyl group) is excellent in terms of heat resistance and water resistance.

Especially when a polymer mixture comprising a styrene polymer is used as the thermoplastic resin (A), the use of the compatibilizer is effective.

For example, when a polymer mixture comprising an aromatic polycarbonate and a styrene polymer is used as the thermoplastic resin (A), it has non-uniformity in the distribution regarding the fraction of the component monomers constituting the copolymer, and therefore different solubility. It is preferable to use a copolymer consisting of copolymer molecules having a parameter (SP) as a compatibilizer.

As mentioned above, the resin composition of this invention can be used as a masterbatch which melt-extrudes with the resin material same or different from thermoplastic resin (A), and optionally with various solid additives. When the resin composition of the present invention is used as a masterbatch as described above, it is possible to melt-extrude a thermoplastic resin having a high viscosity such as polyphenylene ether at a relatively low temperature. Examples of methods for carrying out melt extrusion are methods of simultaneously supplying all materials (including the masterbatch, thermoplastic material other than the thermoplastic resin (A) and optionally solid additives) to the extruder and the masterbatch and thermoplastics ( A resin material comprising a thermoplastic material other than A) and a method of injecting the solid additive into the extruder at its different inlet, wherein the inlet for the solid additive is as defined in the extrusion direction of the extruder.

Regarding the additive (B '), there is no particular limitation, and any conventional additive for the polymer can be used. However, it is preferable to use the above nonpolymerizable liquid substance (B) as an additive (B ').

In the conventional production method of the composition of the polyphenylene ether resin and the additive (having high heat resistance), it is necessary to perform melt mixing at 300 to 350 ° C. Therefore, in the above conventional melt mixing method, for example, reaction of end groups of polymers other than hydroxyl groups (as shown in Scheme i, wherein the end groups of polymers are aminoalkyl groups) or Scheme ii As can be seen, polyphenylene ether resins having a methylene bridged structure formed by the Fries potential arise, thereby increasing the hydroxyl group content of the polyphenylene ether resin. Therefore, in the polyphenylene ether resin composition prepared by the conventional melt-mixing method, due to the high content of hydroxyl groups, the molded resin body prepared from the polyphenylene ether resin composition discolors and has poor light stability. there is a problem.

Methylene bridge structure

Upper end of polymer

The inventors have found that the photostability and discoloration resistance of polyphenylene ether resins {not only the content of hydroxyl groups formed due to the generation of methylene bridge structures, but also the polyphenylene ethers inherently possessed (i.e. the top of each polyphenylene ether chain The total hydroxyl group content of the polyphenylene ether resin, including the hydroxyl group present at the terminal), to 100 mol of repeating oxyphenylene units, to a level of 0.5 mol or less, to significantly improve It was found that it can be done.

The inventors have also conducted mixing to obtain a resin composition comprising said excellent polyphenylene ether resin (A ') and additives for polyphenylene ether resin (B') having significantly improved light stability and discoloration resistance. The non-polymerizable liquid substance (B) is run at a temperature in the range of 25 to 300 ° C., and the non-polymerizable liquid substance (B) is maintained at a liquid state at a temperature in the range of 25 to 300 ° C. as an additive for the (A) thermoplastic resin and (B) the thermoplastic resin (A). It has been found to be effective to use a method consisting of mixing one or more nonpolymerizable liquid substances in a liquid state, thereby dissolving or swelling the thermoplastic resin (A) in the nonpolymerizable liquid substance (B). Examples of additives as additives for polyphenylene ether resins (A ') are not limited to those described above as non-polymerizable liquid substances (B). The specific organophosphorus compound is preferably used as a flame retardant which is a preferred additive.

Can be used.

The obtained molded article has an excellent balance of various properties such as flame retardancy, impact resistance, heat resistance and the like. It has further been found that even better flame retardance can be achieved when the total content of residual aromatic vinyl monomers, dimers and trimers in the resin composition is 1% by weight or less. When the total content of the residual aromatic vinyl monomers, dimers and trimers is more than 1% by weight, the flame retardancy is poor because the vinyl compound evaporates and acts as a flammable gas when burning the resin composition.

Example 1 and Comparative Examples 1 to 4

Each of the five forms of the resin composition shown in Table 1 is independently produced by a process selected from the following four processes and evaluated for various properties such as color tone (yellowness: YI). The results are shown in Table 1.

Process i

Using a batch type mixing vessel equipped with a stirrer, the thermoplastic resin (A) is dissolved in the nonpolymerizable liquid substance (B) at the temperature shown in Table 1 while stirring. The product is introduced into a belt conveyor type dry cooler (belt cooler), whereby pellets are obtained.

Process II-1

A twin screw extruder having a main feeder and a subfeeder is used. The thermoplastic resin (A) is fed from the main feeder and the non-polymerizable liquid substance (B) is fed from the subfeeder, followed by melt extrusion at the temperatures shown in Table 1, whereby pellets are obtained.

Process II-2

A twin screw extruder having a main feeder and a subfeeder is used. The thermoplastic resin (A) and the nonpolymerizable liquid substance (B) are fed from the main feeder, and then melt-extruded at the temperatures shown in Table 1, whereby pellets are obtained.

Process III

The nonpolymerizable liquid substance (B) is added to the thermoplastic resin (A) in a small amount and adsorbed to the thermoplastic resin (A), thereby obtaining an adsorption mixture of the thermoplastic resin (A) and the nonpolymerizable liquid substance (B). The mixture is introduced into a belt conveyor cooler (belt cooler), whereby pellets are obtained.

From Table 1, PPE-1 was dissolved as a thermoplastic resin (A) at a temperature of less than 300 ° C. to suppress the formation of OH groups in the PPE unit (see FIGS. 3 and 4), which was prepared by Process I (invention). Regarding the resin composition, it can be observed that the resin composition not only has excellent appearance, color tone, and light stability with respect to that of other resin compositions produced by melt extrusion, but can also be stably produced. On the other hand, in each of the processes II-1 and II-2, the extrusion of the resin composition is unstable when the content of the non-polymerizable liquid substance (B) in the resin composition is about 60% by weight. In addition, the resin composition prepared in Step II-1 (executed under the conditions of melting PPE-1) does not melt, and thus does not contain any undissolved melt of resin having a good appearance; It is poor with respect to color tone and light stability (reference comparative example 3). The resin composition prepared in step II-2, in which the thermoplastic resin (A) and the non-polymerizable liquid substance (B) are supplied from the main feeder and then melt-extruded, contains a large number of cosmetic melts of PPE-1 that are not melted and therefore have poor appearance. Have Particularly in the case of the process III, the resin composition prepared in the process III of adsorbing the non-polymerizable liquid substance (B) to the thermoplastic resin (A) contains a large number of undissolved PPE-1 unmelted melts and therefore has a very poor appearance.

Examples 2 to 17 and Comparative Examples 5 to 28

The resin composition is prepared using the materials and methods (step I or II) as described in Tables 2 to 4, using PPE-1, PC, GPPS and HIPS-1 independently as the thermoplastic resin (A). The obtained resin composition is evaluated for various properties such as color tone (yellowness: YI). The results are shown in Tables 2 to 4 and FIG. 5.

From Tables 2 to 4 and Fig. 5, the resin composition obtained by the method of the present invention, which is carried out by the process I (dissolution) at a temperature of 300 DEG C or lower, is compared with a resin composition obtained by the conventional melt extrusion method. It is clear that the appearance and color are excellent.

Examples 18-34 and Comparative Examples 29-32, and 52-55

The resin composition is prepared using materials and methods (steps I or II) as described in Tables 5 to 7, wherein PPE-1 and GPPS are independently used as the thermoplastic resin (A). The obtained resin composition is evaluated for various properties such as color tone (yellowness: YI). The results are shown in Tables 5 to 7 and FIGS. 6 and 7.

From Tables 5-7 and Figures 6 and 7, the following is observed:

When the production of the resin body is carried out by the step I (dissolution) using a surface modifier such as an anti-sticking agent or a lubricant instead of the non-polymerizable liquid substance (B), since the surface modifier has poor compatibility with the thermoplastic resin (A), Dissolution of the thermoplastic resin (A) with the surface modifier at a high temperature is necessary, which in turn promotes deterioration of the thermoplastic resin (A) and the surface modifier;

The compatibility of oligomeric aromatic phosphate esters with PPE-1 (often, a flame retardant having excellent compatibility with thermoplastic resins, in which the oligomeric aromatic phosphate esters have somewhat inferior compatibility with thermoplastic resins such as PPE-1) is compatible with oligomeric aromatic phosphate esters. Can be significantly improved by the compatibility of monomeric aromatic phosphate esters or GPPS in mixing; And

With respect to step II-1 (melt extrusion), extrusion can be stably performed when the amount of the nonpolymerizable liquid substance (B) is 20% by weight or less relative to the total weight of (A) and (B); Extrusion is unstable when the amount of the nonpolymerizable liquid substance (B) exceeds 20% by weight.

Examples 35-50 and Comparative Examples 33-34

The resin composition is prepared using the materials and methods (step I) as described in Tables 8 and 9. The obtained resin composition is evaluated for various properties such as color tone (yellowness: YI). The results are shown in Tables 8 and 9.

From Tables 8 and 9, the following is observed:

When the PPE-1 / nonpolymerizable liquid material (B) (flame retardant) weight ratio is in the range of 30/70 to 70/30, it is possible to obtain a molded resin body excellent in terms of ease of operation;

When a solid material (C), such as an oil absorbent material and an antifouling agent, is added to the component (A) / component (B) mixture having a weight ratio within the above range in an amount in which the mixture is present in the liquid state, the resulting resin mixture does not adhere Not; And

When the component (A) / component (B) mixture (in the liquid state) to which the solid substance (C) is added is uneven or has poor fluidity, the appearance of the produced resin composition is very poor (Comparative Example 34).

A resin composition used as a masterbatch was prepared using the materials and methods shown in Table 10, wherein the dissolution of PPE-1 into a non-polymerizable liquid substance (B) improved the compatibility of component (B) with PPE-1. It carries out in presence of the solvent (D) which acts, and introduce | transduces the resulting resin composition into a belt conveyor type cooling drier (cooling drier). Using a twin screw extruder (ZSK-40 mmØ, manufactured and marketed by Werner Pfleiderer GmbH, Germany), the obtained masterbatch and HIPS-1 were removed with solvents under vacuum of 0.1 mmHg, Melt extrusion is carried out depending on the composition and the preparation conditions, thereby obtaining a final product in pellet form. Using an injection molding machine (Model JSW J100EP manufactured and marketed by Japan Steel Works, Ltd., Japan), the obtained pellets were injection molded at a cylinder temperature of 230 ° C. and a molding temperature of 60 ° C. to obtain test specimens. Is evaluated for various properties such as color tone (yellowness: YI). The results are shown in Table 10.

From Table 10 the following is observed:

Compatibility of the oligomeric aromatic phosphate ester with PPE-1 A small amount of solvent (D) (the oligomer aromatic phosphate ester has relatively poor compatibility with PPE-1 among various flame retardants which usually have excellent compatibility with PPE-1). That can be significantly improved by the addition of;

However, when the amount of the solvent (D) exceeds 100 parts by weight of the thermoplastic resin (A), it becomes difficult to maintain the vacuum condition, so that the solvent (D) remains in the resin composition. Lowering the vicat softening temperature of the resin composition thus prepared (the role of the solvent (D) is secondary, the compatibility between the thermoplastic resin (A) and the non-polymerizable liquid material (B) is relatively low, and the solvent (D) A small addition of is indicative of a satisfactory improvement in compatibility);

When lubricating oil, which is not compatible with the thermoplastic resin (A), is used as the nonpolymerizable liquid substance (B), the amount of the solvent (D) is adjusted in order to achieve satisfactory compatibility between the component (A) and the component (B). Unnecessarily high use is necessary and therefore it is difficult to achieve the vacuum condition, thereby generating the above disadvantages (Comparative Examples 35 and 36);

When manufacturing a resin composition by the method of disperse | distributing a nonpolymerizable liquid substance (B) to a thermoplastic resin (A), since the thermoplastic resin (A) does not melt | dissolve in a nonpolymerizable liquid substance (B), the external appearance of the manufactured resin composition Is very poor (Comparative Examples 37 and 38);

When polyamide (PA) is used as the thermoplastic resin (A) and phosphate ester (PB) as the nonpolymerizable liquid substance (B), which is very poor in compatibility between components (A) and (B), solvents (FA) A large amount of) dissolves the PA unevenly in the PB; When the resulting mixture is used as the masterbatch in the second stage, phase separation occurs during removal of the solvent (Comparative Examples 50 and 51).
