Abstract
Abstract A polyphenylene ether resin composition having improved solvent resistance comprising (A) a modified polyphenylene ether obtained by modifying a polyphenylene ether with a modifier such as maleic anhydride and (B) a modified polyolefin obtained by modifying a polyolefin with both a modifier such as maleic anhydride and a vinyl or vinylidene compound such as styrene, and optionally (C) a binder such as phenylenediamine.
