Definitions
- the present invention relates to a method for making poly(arylene ether)- polyamide compositions.
- Poly(arylene ether) resins are characterized by a unique combination of chemical, physical and electrical properties over a broad temperature range. This combination of properties renders poly(arylene ether)s suitable for a wide range of applications.
- the usefulness of poly(arylene ether) resins is limited as a consequence of their poor processability, impact resistance and chemical resistance.
- Poly(arylene ether)-polyamide compositions as disclosed by Finholt (U.S. Pat. No. 3,379,792), overcame processability issues.
- the advantages of the Finholt invention are limited by the fact that when the concentration of the polyamide exceeds 20 weight percent (wt%), appreciable losses in other physical properties result. Specifically, there is no, or at best poor, compatibility between the poly(arylene ether) and tht polyamide such that phase separation of the resin occurs on molding or the molded article is inferior in mechanical properties.
- Compatibilized poly(arylene ether)-polyamide compositions have been produced utilizing a variety of base resins and compatibilizing systems. These thermoplastic products offer a wide range of beneficial properties which take advantage of the strengths of the basic resins while improving upon the weaknesses of each. Among the most useful properties of compatibilized poly(arylene ether)- polyamide compositions are excellent heat resistance, chemical resistance, impact strength, hydrolytic stability and dimensional stability. Such compatibilized poly(arylene ether)-polyamide compositions have found great utility in exterior automotive applications such as body panels. Examples of compatibilized poly(arylene ether)-polyamide compositions can be found in U.S. Pat. No. 4,315,086.
- Polyfunctional compatibility modifiers can facilitate formation of a copolymer of the poly(arylene ether) and polyamide components. Such a reaction has been readily shown to take place under the time, temperature and shear conditions of typical thermoplastic extrusion processes. Copolymer produced in this fashion may serve as a melt surfactant which stabilizes the morphology of the resinous components of the system. Compatibility may also be achieved by improved interfacial adhesion of the resinous components.
- Poly(arylene ether)-polyamide compositions are usually amenable to many different types of processing operations, such as extrusion, compression molding and injection molding. However under certain conditions, final products resulting from the operations exhibit some imperfections. These imperfections fall into two classes, solid particles visible on the surface and flow disturbance artifacts such as pinholes, "V" shape imperfections, and sinkmarks visible as dents in the surface. These imperfections, which often become magnified when painted, are caused by carbonized particles (also known as pits) which are formed during processing operations such as extrusion and injection molding. Articles formed from poly(arylene ether)-polyamide compositions with surface imperfections are typically rejected, thereby increasing the manufacturing cost.
- a process to produce a poly(arylene ether)-polyamide composition comprising creating and maintaining a substantially inert atmosphere in an extruder; combining poly(arylene ether) resin and an optional compatibility modifier in said extruder to form a mixture; compounding said mixture; and adding polyaniide to said mixture and further compounding to form the poly(arylene ether)-polyamide composition.
- the process for producing a poly(arylene ether)-polyamide composition comprises creating and maintaining a substantially inert atmosphere in an extruder; combining poly(arylene ether) resin, an optional compatibility modifier, and up to about 20 wt% polyamide resin in said extruder to form a mixture; compounding said mixture; and adding additional polyamide resin to said compounded mixture and further compounding to form the poly(arylene ether)- polyamide composition.
- Also part of the invention is a process for forming an article from a poly(arylene ether)-polyamide composition, comprising creating and maintaining an inert atmosphere in a molding device; adding the poly(arylene ether)-polyamide composition to the molding device; melting the poly(arylene ether)-polyamide composition; forcing said molten composition into a mold; and cooling said mold and releasing the resulting article.

- compatibility modifiers within this group include trimellitic anhydride acid chloride, chloroformyl succinic anhydride, chloro formyl succinic acid, chloroformyl glutaric anhydride, chloroformyl glutaric acid, chloroacetyl succinic anhydride, chloroacetylsuccinic acid, trimellitic acid chloride, and chloroacetyl glutaric acid.
- trimellitic anhydride acid chloride is preferred. Furthermore, it is especially preferred that compatibility modifiers of this group be prereacted with at least a portion of the poly(arylene ether) whereby the compatibility modifier is a poly(arylene ether)-functionalized compound.
- the foregoing compatibility modifiers may be used alone or in various combinations comprising at least one of the above mentioned compatibility modifiers. Furthermore, they may be added directly to the melt blend or pre-reacted with either or both the poly(arylene ether) and polyamide, as well as with other resinous materials employed in the preparation of the compositions. With many of the foregoing compatibility modifiers, particularly the polyfunctional compounds, even greater improvement in compatibility is found where at least a portion of the compatibility modifier is pre-reacted, either in the melt or in a solution of a suitable solvent, with all or a part of the poly(arylene ether). It is believed that such pre- reacting may cause the compatibility modifier to react with the polymer and, consequently, functionalize the poly(arylene ether) as noted above.
- the poly(arylene ether) may be pre-reacted with maleic anhydride to form an anhydride functionalized poly(arylene ether) which has improved compatibility with the polyamiue compared to a non-functionalized poly(arylene ether).
- the initial amount used will be dependent upon the specific compatibility modifier chosen and the specific polymeric system to which it is added.
- the amount of compatibility modifier used should be sufficient to prevent phase separation of the poly(arylene ether) and polyamide.
- the typical amounts are up to about 10 wt%, with about 0.05 to about 5.0 wt% preferred, and about 0.1 to about 3 wt% especially preferred.
- the composition can also include effective amounts of at least one additive selected from impact modifiers, release agents, stabilizers, organic and/or inorganic fillers, conductive agents, UV stabilizers, anti-oxidants, flame retardants, drip retardants, dyes, pigments, colorants, stabilizers, small particle mineral (such as clay, mica, talc and the like), antistatic agents, plasticizers, lubricants, and mixtures comprising at least one of the above mentioned additives.
- additives are known in the art, as are their effective levels and methods of incorporation. Effective amounts of the additives vary widely, but they are usually present in an amount up to about 50 wt% or more, based on the weight of the entire composition.
- Especially preferred additives include hindered phenols, thio compounds and amides derived from various fatty acids. The preferred amounts of these additives generally ranges up to about 3 wt%.
- additives for conductivity carbon black, carbon fibrils, carbon fibers, carbon nanofibers, carbon nanotubes, carbon particles, and combinations comprising at least one of the above mentioned additives.
- the composition comprising the above mentioned components can be prepared in numerous fashions. As described earlier, the process comprises several components, which can be employed singly or in combination.
- the general procedure comprises: introducing the poly(arylene ether) resin, preferably air free, optionally up to 20 wt% polyamide resin, with up to about 15 wt% preferred, and about 5 to about 10 wt% especially preferred, and optionally a compatibility modifier and other additives, to an extruder or similar mixing device, preferably with an inert atmosphere, to form a mixture.
- the mixture is melted and compounded, preferably under an inert atmosphere, prior to adding the remaining polyamide.
- an extruder with an atmospheric vent as described below, it is preferable to operate with the atmospheric vent open.
- the remaining polyamide is added, preferably under an inert atmosphere, and the resulting mixture is then further melted, compounded, and finally palletized preferably by underwater pelletization, or otherwise finally processed by any method known in the art.
- Air free poly(arylene ether) can be obtained by flushing the poly(arylene ether) particles with an inert gas a sufficient number of times such that the resin is substantially free of gaseous oxygen.
- Inert gases include all gases which are unreactive towards poly(arylene ether), polyamide or other components of the composition. Possible inert gases include hydrogen, helium, neon, argon, nitrogen, carbon dioxide, and the like, and mixtures comprising at least one of the above mentioned gases, with nitrogen preferred.
- Poly(arylene ether) particles are porous and as a result gaseous oxygen can infiltrate the interior of the particles. Flushing the particles removes this oxygen which can cause oxidation of the poly(arylene ether) and therefore the formation of carbon particles. As stated earlier, carbon particles cause surface imperfections.
- the extruder preferably has an inert atmosphere obtained by flushing the extruder with an inert gas so as to substantially remove the gaseous oxygen contained within.
- the inert atmosphere is preferably maintained during addition of the above mentioned components by a continuing flow of inert gas.
- the flow rate can be up to or exceeding about 20 liters of inert gas per kilogram of poly(arylene ether) (1 N 2 kg PPE), with about 1 liter inert ga:> kg poly(arylene ether) to about 15 liters inert gas/kg poly(arylene ether) preferred, ar.d about 6 liters inert gas/kg poly(arylene ether) to about 13 liters inert gas/kg poly(arylene ether) especially preferred.
- the flow rates of the various components which is determined by the screw design and geometry of the extruder, can be determined by an artisan without undue experimentation.
- Possible extruders include all conventional devices capable of intimately mixing the components and maintaining the desired environment, for example single screw, twin screw or other multiple screw extruders, as well as other mixing devices such as kneaders and the like capable of effectively mixing the composition. Due to mixing requirements and environmental controls, an extruder having at least two feed ports with an atmospheric vent there between is preferred, with an extruder having at least two feedports, an atmospheric vent and at least one vacuum vent especially preferred.
- the resin(s), additives and optional modifiers are intimately mixed at a temperature sufficient to melt and compound the poly(arylene ether), e.g. typically about 250°C to about 320°C, and preferably about 275°C to about 305°C.
- the r maining polyamide is then added and the mixture is further mixed so as to obtain the desired product.
- the resulting polymer is then put through a die, roller, or other final processor, and formed into pellets, sheets, a web or the like, by any method known in the art, with underwater pelletization preferred.
- the various initial components e.g. the poly(arylene ether) resin, the portion of the polyamide resin, compatibility modifier, and optional impact modifier and other additives, can be premixed.
- This mixture can then be flushed with an inert gas so as to obtain a mixture which is substantially free of gaseous oxygen.
- the flushed mixture is then added to the extruder or other appropriate mixing device, with an inert atmosphere under the flow of an inert gas as described above. From the extruder the mixture is pelletized, formed into a sheet, or otherwise processed as is conventional.
- the processed mixture can be uti Sized to form various articles, such as automotive parts.
- One technique of forming these parts comprises injection molding; a method commonly utilized to form articles from polymer resins. This process involves adding the mixture to a feed hopper, heating the mixture to a temperature sufficient to melt the mixture and forming the mixture into the desired shape by forcing it into a mold. Again, to further prevent the formation of pits, it is preferable to use inert gas(es) to create and maintain an inert atmosphere over the mixture during this processing.
- the preferred inert atmosphere during article formation comprise the use of inert gas as described above, with the use of nitrogen and hydrogen more preferred.
- the nitrogen-hydrogen mixture can be about 90 volume percent (vol%) to about 99 vol% nitrogen, with about 93 vol% to about 98 vol% preferred.
- Other conventional further processing techniques can also be employed. All patents cited are incorporated herein by reference. The invention is further illustrated by the following non-limiting examples.
- a WP-28 Werner and Pfleiderer twin screw extruder was used with a main feeder disposed at the front-end of the extruder and a second feeder located approximately halfway down the extruder with an atmospheric vent located between the two feeders and a vacuum vent located between the downstream feeder and the die of the extruder.
- Nitrogen was introduced via a pipe at the bottom of the main feeder to flush the extruder and maintain the nitrogen atmosphere during the addition of ingredients.
- the nitrogen flow rate was monitored with a flow meter.
- the extruder was operated using the parameters defined in Table 1.
- Feeder % is the percentage of the total throughput of the extruder.
- the poly(arylene ether)-polyamide composition comprised about 50 wt% poly(arylene ether) and additives and about 50 wt% polyamide. Molding was done on a KM350, forming DIN A5 plaques for molding with inert atmosphere while for the standard molding conditions 4 cm x 4 cm plaques were used. The 4 cm x 4 cm plaques were formed by injection molding with a low injection speed and the plaque was not completely filled. Low injection speed is defined as the minimal speed of injection required to obtain a good quality plaque. The plaques were not completely filled in order to improve the visibility of the defect. Incomplete filling makes the carbonized particles surface at the flow end of the plaque.
- the plaques were evaluated for pits by two methods.
- the first method involved a visual inspection and quantification of the number of surface defects.
- the second method was a filtration test.
- the plaque was dissolved in a mixture of chloroform and trifluoroacetic acid. The solution was then filtered and the amount of insoluble was evaluated using automatic image analysis software. This method of evaluation is also known as the insolubles test.
- Examples 1-3 use the same procedure with varying nitrogen flow rates.
- No polyamide was introduced through the first feeder of the extruder.
- 3.67 kilograms (kg) of poly(arylene ether) and additives, 0.8 kg of styrene ethylene propylene, 0.7 kg of styrene ethylene butylene styrene, and 0.65 kg of citric acid were introduced to the main feeder with nitrogen flow.
- 4.8 kg of polyamide were introduced at the second feeder and processing continued.
- the resulting composition was then pelletized and formed into plaques.
- the plaques were evaluated for pits and insolubles as shown in Table 2.
- the nitrogen flow rates for Examples 1-3 were 1.2 liter per kg (1/kg), 5.5 1/kg, and 11.5 1/kg, respectively.
- the control material was made without nitrogen flow.
- Examples 12 - 13 A molding trial was done on a KM350 with a compatibilized poly(arylene ether)-polyamide composition molding DIN A5 plaques using the conditions shown in Table 6.
- the feed hopper of the molding machine was flushed with an inert gas. A slight over pressure was maintained to ensure an oxygen level below 1 vol% in feed hopper (oxygen level of about 0.02 vol% or less typically achieved).
- Example 12 In the control no inert gas was used; in Example 12 the inert gas was nitrogen; and in Example 13 the inert gas was a mixture of nitrogen and hydrogen gas (97 vol% N / 3 vol% H 2 ). The plaques were evaluated for pits and insolubles. Results are shown in Table 7.
- the present invention reduces pits by namely compounding under an inert atmosphere, flushing the poly(arylene ether) with an inert gas, operating the extruder with the atmospheric vent open, and or adding up to 20 wt% of polyamide in the first compounding step.
- the beneficial effect of compounding under an inert atmosphere is clearly seen in Examples 1-3 where the number of pits per plaque was reduced from 20 in the control to 2.3 in Example 3. The number of insolubles showed a similar drop from 3294 in the control to 637 in Example 3.
- a comparison of Examples 4 and 5 clearly shows the benefit of flushing the poly(arylene ether) resin with nitrogen.
- Examples 4 and 5 are both compounded under an inert atmosphere but in Example 5 the poly(arylene ether) resin is flushed with nitrogen.
- Example 5 The number of pits per plaque was further reduced by 1 in Example 5 when compared to Example 4 and the number of insolubles is reduced from 1 151 in Example 4 to 500 in Example 5.
- the advantage of operating with the atmospheric vent is clearly seen in Example 1 1.
- Examples 6 through 9 demonstrate the utility of adding a portion of the polyamide at the main feeder as evidenced by a dramatic drop in the number of pits per plaque from the Control (20) to Example 8 (4.2). A similar trend is seen in the insolubles data.
- each improvement to the process results in a decrease in the number of pits/insolubles and the combination of improvements results in a greater decrease in pits/insolubles.
- the improvements to the injection molding process may be used in combination with improvements to the process of making poly(arylene ether)- polyamide compositions or separately.
- the amount of carbonized particles formed during injection molding of poly(arylene ether)-polyamide polymer compositions was distinctly reduced when the feed hopper was flushed with an inert gas or mixture of gases and a slight over pressure of inert gas was maintained.
- poly(arylene ether)- polyamide compositions can be produced having a significantly reduced number of carbon particles and/or insolubles.
- the poly(arylene ether)-polyamide composition comprises an about 50% or greater reduction of carbon particles, with about 75% or greater reduction preferred, about 85% or greater more preferred and about 90% or greater reduction especially preferred. Additionally, an about 50% or greater reduction in insolubles has been achieved with an about 70% or greater reduction preferred, about 80%) or greater reduction more preferred, and an about 85% or greater reduction especially preferred.
