Abstract
The present invention relates to a thermoplastic resin composition and a method for making the same. The method for manufacturing a thermoplastic resin composition comprises introducing carbon fibrils and a polyamide into a first mixture comprising a polyphenylene ether, a polyamide, and a compatibilizing agent to provide a second mixture comprising, based upon the total weight of the second mixture: about 10 to about 50 wt. % of the polyphenylene ether, about 35 to about 65 wt. % of the polyamide, about 0.4 to about 3 wt. % of the carbon fibrils, and about 0.4 to about 3 wt. % of the compatibilizing agent; and blending the second mixture at a temperature sufficient to melt the polyphenylene ether.

A method for manufacturing a thermoplastic resin composition, comprising:
- introducing carbon fibrils and a polyamide into a first mixture comprising a polyphenylene ether, a polyamide, and a compatibilizing agent to provide a second mixture comprising, based upon the total weight of the second mixture:
- about 10 to about 50 wt. % of the polyphenylene ether, about 35 to about 65 wt. % of the polyamide, about 0.4 to about 3 wt. % of the carbon fibrils, and about 0.4 to about 3 wt. % of the compatibilizing agent;
- and
- blending the second mixture at a temperature sufficient to melt the polyphenylene ether.
A method for manufacturing a thermoplastic resin composition, comprising:
- introducing carbon fibrils, talc and a polyamide into a first mixture comprising a polyphenylene ether, a polyamide, and a compatibilizing agent to provide a second mixture comprising, based upon the total weight of the second mixture:
- about 10 to about 50 wt. % of the polyphenylene ether, about 35 to about 65 wt. % of the polyamide, about 0.4 to about 3 wt. % of the carbon fibrils, about 5 wt. % to about 40 wt. % talc, and about 0.4 to about 3 wt. % of the compatibilizing agent;
- and
- blending the second mixture at a temperature sufficient to melt the polyphenylene ether.
A method for manufacturing a thermoplastic resin composition, comprising:
- blending a mixture comprising about 10 to about 50 wt. % of a polyphenylene ether, about 35 to about 65 wt. % of a polyamide, about 0.4 to about 3 wt. % of carbon fibrils, about 0.4 to about 3 wt. % of a compatibilizing agent, about 2 to about 10 wt. % of modifier, and about 5 to about 40 wt.% of talc, based upon the total weight of the mixture, at a temperature sufficient to melt the polyphenylene ether.
