Abstract
Abstract A composition comprising a polyphenylene ether, a polyamide resin and a compound having an unsaturated group and a polar group in combination in the same molecule kneaded therein, and optionally an impact resistance improving material kneaded in said kneaded product. Impact resistance can be greatly improved as compared with the composition having the all components kneaded at the same time.
