Thermoplastic resin compositions comprising PPE, polystyrene, an ethylene co-oligomer, diblock copolymers and triblock copolymers

摘要

A resin composition comprising (a) a polyphenylene ether resin or a mixture of it and a polystyrene resin, (b) a co-oligomer of ethylene and an alpha-olefin, (c) optionally an elastomeric hydrogenated A-B-A block copolymer, and (d) optionally an elastomeric hydrogenated A-B block copolymer. The chemical resistance of the polyphenylene ether is improved.
