Abstract

A thermoplastic molding material based on a styrene polymer which has been made impact-resistant, and on a polyphenylene ether, wherein the impact-resistant styrene polymer comprises a soft component which has a mean particle diameter of greater than 0.3 .mu.m and contains an acrylic ester polymer as the elastomeric component. The novel molding materials possess improved flow and give moldings having improved aging resistance.
