Graft copolymer composition of styrene-polyphenylene ether and preparation thereof

摘要

A thermoplastic resin composition containing (I) a graft copolymer of a polyphenylene ether with a styrene type compound, containing substantially no homopolymer of polyphenylene ether, and (II) a graft copolymer of an ethylene copolymer of ethylene and not more than 40 mol percent of at least one unsaturated compound of the formula CH2=CH-OCOR1 or CH2=CR2-COOR3 (wherein R1 denotes an alkyl group having one to four carbon atoms and R2 and R3 each denote a hydrogen atom or an alkyl group having one to four carbon atoms) with a styrene type compound has improved properties such as Izod impact strength, oil resistance and weathering resistance.
