Fuel permeability) and wear resistance such as physical and chemical properties are excellent. Accordingly, interest in carbon monoxide-based polymer resins, which are known as polyketones or polyketone resins, is increasing. US Pat. Nos. 4,880,903 and the like disclose carbon monoxide, ethylene, and talefinic unsaturated hydrocarbons, for example, propylene.

EMBODIMENT OF THE INVENTION Hereinafter, the polyketone resin composition and polyketone resin molded article of this invention are demonstrated in detail.

Polyketone resin composition according to an aspect of the present invention, piketone

1 part by weight or more and less than 100 parts by weight of polyalkylene carbonate is included based on 100 parts by weight.

The polyketone may include one or more repeating units represented by the following Chemical Formula 1.

[ One]

In Chemical Formula 1,

R is

Linear or branched alkylene having 1 to 10 carbon atoms; Arylene having 1 to 10 carbon atoms; Alkyl ether of 1 to 10 carbon atoms; Aryl ethers having 1 to 10 carbon atoms; Alkyl esters having 1 to 10 carbon atoms; a is an aryl ester having 1 to 10 carbon atoms and n is an integer of 10 to 1000.

The polyketone polymer having the above structure is prepared by the reaction of a compound including carbon monoxide and a unsaturated double bond, and in recent years, alternatingly repeated repeating units composed of carbon monoxide and at least one ethylenically unsaturated hydrocarbon There is a growing interest in copolymers and the like. The polyketone polymer thus obtained has a relatively high molecular weight, and is widely used as a high-quality thermoplastic resin having excellent physical properties in molded articles such as food and beverage containers, electronic product housings, and automotive parts.

However, such polyketone polymers, due to the structure containing carbonyl carbon having high reactivity in the molecule, crosslinking reaction proceeds easily during melt processing such as extrusion and injection molding.

More specifically, the poly Kerron aldol condensation reaction within the carbonyl functional group (aldo l condensat i on) is in progress, and the polymer chain can ^'be connected (cross l inking) with each other, whereby the viscosity is raised and processability This can be significantly lowered.

The inventors of the present invention have found that by melting a specific amount of polyalkylene carbonate in a polyketone, the melt stability of the polyketone can be significantly increased, and the present invention has been completed.

In the polyketone polymer structure, the hydrogen around the carbonyl group (carbonyl alpha hydrogen) can easily drop off under high temperature melting conditions. The inoleate anion thus made attacks the surrounding carbonyl central carbon and the water escapes. Aldol condensation reaction may occur, where curing proceeds as it exits.

When the aldol condensation reaction occurs continuously, the viscosity of the resin continuously rises, which increases the load on the processing equipment and, after a certain time, the processing equipment can no longer be operated. In this case, the resin in the installation should be purged with other resins for a long time or restarted after removing the cured resin.

By the way, in the case of polyketone, its molecular structure is similar to that of polyalkylene carbonate, and the compatibility between resins is very good. Also, if there is polyalkylene carbonate around the plyketone, the carbonyl alpha hydrogen is removed in the hot melt state, and the polyalkylene carbonate before attacking the carbonyl central carbon of the polyketone even if inoleate is formed A bond is formed preferentially and the viscosity rise due to the cross lking reaction can be suppressed. Therefore, as a result, the polyalkylene carbonate can suppress the aldol condensation reaction between the polyketones and improve the melt stability of the polyketone even at high temperature conditions. It can be effectively maintained.

Polyketone resin composition according to an aspect of the present invention, polyketone

It is possible to effectively suppress the aldol condensation reaction of the carbonyl carbon in the polyketone by the above-described principle, including 1 part by weight or more and less than 100 parts by weight of polyalkylene carbonate.

Accordingly, when processing the polyketone polymer, it is possible to effectively prevent the phenomenon that the viscosity of the resin continuously rises with time in the hot melt state, and even when the processing equipment is operated for a long time using polyketone, Operation increase for removing the cured resin can be minimized, so that high processability can be maintained.

Specifically, the polyketone resin composition according to an embodiment of the present invention, for the above-described effect, with respect to 100 parts by weight of polyketone, 1 part by weight or more, more preferably about 5 parts by weight or about 10 parts by weight of poly Alkylene carbonate may be included, and less than 100 parts by weight, or less than about 60 parts by weight, more preferably about 50 parts by weight with respect to 100 parts by weight of polyketone in a range that does not impair the basic chemical and physical properties of the polyketone Or up to about 25 parts by weight of polyalkylene carbonate.

When the polyalkylene carbonate is used in an amount less than the above range, it may not effectively suppress the aldol condensation of the polyketone, there may be a problem that the above-described effects of the present invention that can improve the melt stability at high temperature may not meet the expectations When the polyalkylene carbonate is used too much, a problem may occur in which the inherent mechanical properties of the polyketone are lowered.

According to one embodiment of the invention, the polyketone, it may be preferred that the aliphatic polyketone containing ethylene, propylene, isopropylene, butylene units, binary copolymer containing one or more such repeating units, It may be more desirable to use black silver in the form of terpolymers.

The polyketone may have a weight average molecular weight of about 10, 000 to about l, 000, 000 g / mol.

According to another embodiment of the present invention, the polyalkylene carbonate may include a repeating unit represented by Formula 2 below. [Formula 2]

In Chemical Formula 2,

R ¹ to R ⁴ are each independently hydrogen, 1 to _. A linear or branched alkyl group of 20, an aryl group of 6 to 20 carbon atoms, an alkenyl group of 1 to 20 carbon atoms, or a cycloalkyl group of 3 to 20 carbon atoms; Any two of R ¹ to R ⁴ may be linked to each other to form a cycloalkyl group having 3 to 10 carbon atoms;

m is an integer of 10-1, 000.

In this case, the polyalkylene carbonate may have a weight average molecular weight of about 10, 000 to about l, 000, 000 g / mo l, preferably, about 50, 000 to about 500, 000 g / ii) l, As the polyalkylene carbonate has the polymerization degree and the increased average molecular weight, the molded article obtained therefrom may exhibit mechanical properties such as appropriate strength and flexibility.

Specifically, the polyalkylene carbonate may be, for example, at least one selected from the group consisting of polyethylene carbonate, polypropylene carbonate, polypentene carbonate, polynuxene carbonate, polyoctene carbonate, polycyclonuxene carbonate, and copolymers thereof. have.

The polyalkylene carbonate is an amorphous polymer containing a repeating unit represented by the above formula.

In addition, ^"the polyalkylene carbonate while having from about 40 ^° C or less, for example, a relatively low glass transition temperature (Tg) of from about 10 to about 40 ^° C can be controlled within this range.

Although the manufacturing method of the polyalkylene carbonate used for this invention is not specifically limited, For example, it can obtain by copolymerizing an epoxide type compound and carbon dioxide. Or by ring-opening polymerization of cyclic carbonates. Copolymerization of the alkylene oxide and carbon dioxide can be carried out in the presence of metal complexes such as zinc, aluminum, and cobalt. When the polyalkylene carbonate is prepared by copolymerization using an epoxide compound and carbon dioxide in the presence of an organometallic catalyst, the epoxide compound is ethylene oxide, propylene oxide, 1-butene oxide 2-butene oxide, isobuty. Ethylene oxide, 1-pentene oxide, 2-pentene oxide, 1-nuxene oxide, 1-octene oxide, cyclopentene oxide, cyclonuxene oxide, styrene oxide or butadiene monooxide, etc. It may be a compound, but is not limited thereto.

Such polyalkylene carbonate may be a homopolymer including a repeating unit represented by Formula 2; Or a copolymer including two or more repeating units belonging to the formula (2), or a copolymer including an alkylene oxide-based repeating unit together with the repeating unit represented by the formula (2).

However, the polyalkylene carbonate is a repeat represented by the formula (2) so that the specific physical properties (for example, strength, elongation, flexibility or low glass transition temperature, etc.) due to the repeating unit represented by the formula (2) can be maintained. It may be a co-polymer comprising at least one kind of unit at least about 40 wt%, preferably at least about 60 wt%, more preferably at least about 80 wt%.

According to one embodiment of the present invention, the polyalkylene carbonate may be, for example, polyethylene carbonate, polypropylene carbonate, polypentene carbonate polynuxene carbonate, polyoctene carbonate, polycyclonuxene carbonate, or a copolymer thereof However, the present invention is not limited thereto, and R1 to R4 may be selected as appropriate functional groups in consideration of the physical properties of the resin to be finally obtained and the blend with the polyketone.

For example, when the functional group is hydrogen or a functional group having a relatively small carbon number, it may be more advantageous in terms of flexibility and compatibility with polyketone. When the functional group has a relatively large carbon number, the mechanical properties such as the strength of the resin may be used. It may be advantageous from the side.

And, in the polyalkylene carbonate, the degree of integration m of the repeating unit represented by Formula 2 is about 10 to about 1,000, preferably about 50 to about It can be 500. According to another embodiment of the present invention, the polyketone resin composition may be 1 to 30 parts by weight of polylactide, based on 100 parts by weight of the polyketone.

The polylactide may primarily improve the thermal stability of the polyalkylene carbonate, and thus serves to more stably perform the kneading of the polycarne and the polyalkylene carbonate. When the polylactide is contained in an amount less than the above range, when the polyketone and the polyalkylene carbonate are stirred at a high temperature, the decomposition of the polyalkylene carbonate may occur, and when the polylactide is included in the above range, Problems may occur in which the physical properties of the polyketone are lowered.

Lactide may be generally classified into L-lactide composed of L-lactic acid, D-lactide composed of D-lactic acid, and meso-lactide composed of one L-form and one D-form. In addition, the mixture of L-lactide and D-lactide by 50:50 is called D, L-lactide or rac-lactide. Among these lactides, polymerization using only L-lactide or D-lactide with high optical purity is known to give L- or D-polmolactide (PLLA or PDLA) having very high stereoregularity. Lactide is known to have higher crystallization rate and higher crystallization rate than polylactide having low optical purity. However, the term "lactide monomer" herein is defined to include all types of lactide regardless of the difference in the properties of lactide according to each form and the difference in the properties of the polylactide formed therefrom.

The molecular structure of the polylactide may be polymerized from L-lactic acid, D-lactic acid or L'D-lactic acid. The polylactide may be prepared by the step of forming the following repeating unit by the lactide monomer and the ring-opening polymerization, and the polymer after the formation of the ring-opening polymerization and the formation of the repeating danbu may be referred to as the polylactide. . In this case, the lactide monomer may include all types of lactide as described above.

According to an embodiment of the present invention, the polylactide has a degree of polymerization of about Preferably it may be 50 to 500, and may have a weight average molecular weight of about 10, 000 to about l, 000, 000g / ii) l. As the polylactide has the polymerization degree and the weight average molecular weight, the polyketone resin composition can maintain the basic physical properties of the polyketone therefrom, and excellent thermal stability can be obtained even at a high temperature melting state.

The category of the polymer which may be referred to as “polylactide” includes polymers in all states after the ring-opening polymerization and the formation of the repeating unit are completed, for example, in the crude or purified state after the ring-opening polymerization is completed. The polymer, the polymer included in the liquid or solid resin composition before the molding of the product, or the polymer contained in the plastic or woven fabric, such as product molding is all may be included. As a method for producing polylactide, a method of directly condensing lactic acid or ring-opening polymerization of the lactide monomer under an organometallic catalyst is known. In the ring-opening polymerization method of lactide monomers, the lactide monomer must be prepared first from lactic acid, which makes the manufacturing process more complicated and requires higher cost than polycondensation polymerization. However, the resin has a relatively large molecular weight through lactide ring-opening polymerization using an organometallic catalyst. Can be obtained relatively easily and control of the polymerization rate is advantageously applied commercially. Due to this characteristic composition, the polyketone resin composition according to an embodiment of the present invention may have a viscosity increase rate of about 10% or less at about 240 ^° C. More specifically, the polyketone resin composition has a viscosity increase rate of about 10% or less, or about 0 to about 10% within 300 seconds when exposed to a temperature condition of about 240 ^° C., the viscosity hardly rises, The viscosity may be lowered, and workability may be very excellent.

Various additives can be added to the polyketone resin composition of this invention according to a use. Examples include, but are not limited to, additives for modification, coloring agents (pigments, dyes, etc.), fillers (carbon black, titanium oxide, talc, calcium carbonate, clay, etc.). Modified additives include dispersants. Lubricants, plasticizers, flame retardants, antioxidants, antistatic agents, light stabilizers, ultraviolet absorbers, crystallization accelerators and the like. Various additives may be used to pellet pellets from a polyalkylene carbonate resin composition. It may be added at the time of manufacture or when molding a pellet to produce a molded object.

As a manufacturing method of the polyketone resin composition of this invention, various well-known methods can be used. As a method of obtaining a homogeneous mixture, for example, the above-described polyketone, polyalkylene carbonate, polylactide and the like are added at a constant ratio, and a Hansel mixer, a ribbon blender, a blender, and a blender are blended. And the like may be mixed.

As the melt kneading method, a VAN Antonie Louis Barye mixer, a single or two-axis compressor, or the like can be used. The shape of the resin composition of the present invention is not particularly limited, and for example, a fluid, a strand, a sheet, a plate, a pellet, or a pellet in which the mixture is molten. It may be processed by let).

According to still another aspect of the present invention, a polyketone resin molded article manufactured using the polyketone resin composition described above is provided.

Such molded articles may include films, film laminates, sheets, filaments, nonwoven fabrics, injection molded articles, and the like.

Hereinafter, the operation and effects of the invention will be described in more detail with reference to specific embodiments of the invention. However, these embodiments are only presented as an example of the invention and thereby the scope of the invention is not determined.

Polyethylene carbonate resin manufacturing

Polyethylene carbonate resin was prepared by copolymerizing ethylene oxide and carbon dioxide using a diethyl-zinc catalyst by the following method (Journal of Polymer Science B 1969, 7, 287; Journal of Controlled release 1997, 49, 263).

A dry diethyl-zinc catalyst (lg) and a dioxane solvent (10 mL) were added to an autoclave reaction vessel equipped with a stirrer, and purified water O.lg diluted in 5 mL dioxane solvent was added slowly with stirring. After layering about 10 atm of carbon dioxide, the mixture was stirred at 120 ^° C for 1 hour. Thereafter, purified ethylene oxide (10 g) was added, and carbon dioxide was further layered at about 50 atm, and then the temperature was adjusted to 6 (C for 48 hours. After the reaction, unreacted ethylene oxide was removed under low pressure and dichloromethane solvent was added. Washed with an aqueous hydrochloric acid solution (0.1 M) and precipitated in methanol to obtain a polyethylene carbonate resin, which was about 15 g in weight, and its production was confirmed by nuclear magnetic resonance spectrum, and was analyzed by GPC. Was found to be about 174,000 g / mol Polylactide Blended Pellets Preparation

To the prepared polyethylene carbonate, polylactide (NatureWorks PLA

3001D) were mixed and pellets were prepared so that the content of polylactide was 5 3/4.

Example 1

50 g polyalkylene carbonate (weight average molecular weight: 174,000 g / mol,

NatureWorks PLA 3001D 5wt%) pellets and 450 g polyketone (Hyosung, M620A) pellets were dry blended at room temperature.

The resin composition thus prepared was prepared in pellet form using a twin screw extruder (BA—19, BAUTECH), and the obtained pellet form resin composition was dried in a vacuum oven at 40 ^° C. overnight. . Example 2:

100 g polyalkylene carbonate (weight average molecular weight: 174,000 g / mol, with 5 wt% of NatureWorks PLA 3001D) pellets, 400 g polyketone (Hyosung, M620A) The pellet was dry blended at room temperature.

The resin composition thus prepared was prepared in pellet form using a twin screw extruder (BA-19, BAUTECH), and the obtained pellet form resin composition was dried in a vacuum oven at 40 ^° C. overnight. . Comparative example 1:

500 g of polyketone (Hyosung, M620A) pellets were used after drying overnight in a vacuum oven at 40 ^° C. Comparative Example 2: Polyketone Re-Extrusion

500 g of polyketone (Hyosung, M620A) pellets were re-extruded using a twin screw extruder (BA-19, BAUTECH) to produce pellets, and the resulting pellet-type resin composition was vacuum oven at 40 ^° C. It was used after drying overnight at.

Experimental Example

The pellets prepared in Examples and Comparative Examples, using a rotary rheometer (ARES G2, TA instrument), was measured for viscosity changes with time at 240 ^° C. 1 is a graph of the polyketone resin composition according to Examples and Comparative Examples of the present invention measured and measured for 10 minutes (600 seconds) of viscosity change with temperature.

Referring to FIG. 1, in the case of Comparative Example 1 using only polyketone alone, and Comparative Example 2 in which polyketone was reextruded, it can be confirmed that the viscosity is continuously increased over time.

This is a phenomenon that occurs in polyketone resins, after nucleophilic addition to carbonyl groups, as aldol condensation reaction occurs, and crosslinking between polymer chains proceeds.

However, according to the embodiment of the present invention, polyethylene carbonate It can be confirmed that it is added to effectively suppress the aldol condensation reaction between the polyketone polymer chain.

Specifically, in the case of Example 1, the viscosity initially increases slightly at high temperature, but it shows a high melt stability within a short time, it can be confirmed that the viscosity is reduced, in the case of Example 2, almost no increase in viscosity from the beginning You can clearly see that.

FIG. 2 is a graph illustrating a change in viscosity according to temperature of an example of a polyketone resin composition according to Examples and Comparative Examples of the present invention measured for 1 hour (3,600 seconds).

Referring to FIG. 2, it can be seen that the melt stability effect of the polyalkylene carbonate is maintained not only for a short time but also for a long time. Accordingly, it can be confirmed that the polyketone resin composition according to the embodiment of the present invention has a high melt stability for a long time, and may have excellent workability even at high temperature processing conditions such as molding. .
