The present invention relates to a thermoplastic resin composition and a method for making the same. The composition comprises the reaction product of about 10 wt % to about 50 wt % polyphenylene ether, about 35 wt % to about 65 wt % polyamide, preferably about 0.4 wt % to about 3.0 wt % carbon fibrils, and optionally about 5 wt % to about 40 wt % talc, up to about 10 wt % compatibilizing agent and up to about 20 wt % impact modifier. The method comprises forming a carbon masterbatch with polyamide and introducing the masterbatch and the polyamide subsequent to compounding the polyphenylene ether with a compatibilizing agent.

Conductive polyphenylene ether-polyamide blend

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.

The method comprises forming a carbon masterbatch with polyamide and introducing the masterbatch and the polyamide subsequent to compounding the polyphenylene ether with a compatibilizing agent.

The invention relates to a method of making a conductive thermoplastic composition containing at least one dispersed phase polymer with a continuous phase polymer and at least one conductivity imparting agent wherein the bulk resistivity of the composition is at least partially determined by the particle size of the dispersed phase within the continuous phase. The thermoplastic composition preferably comprises a compatibilized blend of at least one polyphenylene ether resin, at least one polyamide resin, and at least one conductivity imparting agent, and optionally, one or more of impact modifiers, stabilizers, antioxidants, lubricants, and fillers.
