Abstract
An ipact-resistant polyamide resin composition which comprises PA1 (a) a polyamide resin (hereinafter abbreviated as PA), PA1 (b) a polyphenylene ether type resin (hereinafter abbreviated as PPE), and PA1 (c) a hydrogenated block copolymer type elastomer (hereinafter abbreviated as TPE) which is a copolymer containing a vinyl aromatic compound polymer block A and an olefinic compound polymer block B, the degree of unsaturation of the block B not exceeding 20%, the diameter of the dispersed phase of PPE dispersed in the said composition being 0.6 .mu.m or less, and the insoluble portion of the composition remaining after extraction thereof with formic acid followed by chloroform being 20% by weight or more relative to the total amount of PPE and TPE present in the composition, and a process for producing the same.
