Abstract
A polyphenylene ether/polyamide resin composition comprising: (A) polyphenylene ether modified with an unsaturated carboxylic acid having (a) an ethylenically unsaturated double bond and (b) either a carboxyl group or an acid anhydride group, (B) 6,6-nylon, (C) 6-nylon, and optionally (D) a montanic acid metal salt. This composition is possesses good flowability, heat resistance, solvent resistance, dimensional stability, and moreover good releasability from a mold and recyclability on the basis of advantages of polyphenylene ether (PPE) and polyamide, and can be used for manufacturing automobile parts such as wheel caps, fenders, bumpers and spoilers, or housings for office automation machines, etc.
