ABSTRACT:
A polyphenylene ether resin composition comprising a polyphenylene ether resin and a rubber modified resin, said rubber modified resin containing a discontinuous elastomeric rubber phase dispersed in a continuous resin phase comprising a copolymer of a vinyl cyanide compound and a vinyl aromatic compound or a mixture of a homopolymer of a vinyl aromatic compound and a copolymer of a vinyl cyanide compound and a vinyl aromatic compound, said elastomeric rubber phase comprising a grafted elastomeric rubber which has a graft phase of a copolymer of vinyl cyanide compound and a vinyl aromatic compound and having a grafting degree of 35 to 300% by weight, the contents of vinyl cyanide compound in the graft phase and resin phase being 12 to 30% by weight and 3 to 10% by weight, respectively. The polyphenylene ether resin composition of the present invention is excellent in solvent resistance and colorability as well as impact strength.
