Abstract
Abstract A polyphenylene ether resin composition contains, (i) 100 parts by weight of a polyphenylene ether, (ii) 0 to 400 parts by weight of an aromatic vinyl polymer (I), and (iii) one or more other components compatible with the polyphenylene ether, which composition has an excellent impact resistance, heat resistance, water resistance, moldability, and solvent crack resistance, and is obtained at a low cost.
