Polyamide resin compositions.

摘要

A polyamide resin composition which comprises: (A) an aromatic polyamide resin comprising a dicarboxylic acid component comprising an aromatic dicarboxylic acid and a diamine component comprising at least one aliphatic diamine or alicyclic diamine; (B) a fibrous reinforcement; and (C) at least one additive which is a group I, II or III metal salt of a higher fatty acid or an acid ester, partially saponified ester or metal salt of an aliphatic carboxylic acid of 26-32 carbons. The resin composition has high fluidity and mold-releasing properties as well as high heat resistance and rigidity, and can be molded without decomposition of the resin.
