ABSTRACT:
A thermoplastic resin composition having in admixture a polyphenylene ether resin and an elastomeric block copolymer wherein the block copolymer has in admixture a triblock copolymer A-B-A' and a diblock copolymer A-B with A and A' being polymerized vinyl aromatic hydrocarbon blocks such as styrene and B being an ethylene-alkylene block such as ethylene-butylene. The composition of this invention can also include other additives such as siloxane fluids, flame retardants, polyolefins, and phosphates, as well as fillers, etc. Also included in this invention is the process of preparing such compositions and articles of manufacture prepared therefrom, such as electrical conductor articles or formed articles. The compositions of this invention provide improved flexibility and elongation.
