Abstract

The mechanical properties of polymer mixtures which comprise a polyphenylene ether, a polyamide, and an agent to improve the impact strength can be improved by using as an agent to improve the impact strength a mixture consisting of PA0 (a) 10-90 parts by weight of a partially hydrogenated diene-vinylaromatic diblock copolymer and, PA0 (b) 90-10 parts by weight of a partially hydrogenated diene-vinylaromatic polyblock copolymer having at least three blocks.
