Abstract

Soft polymer mixtures of PA1 (a) 10 to 50 parts by weight of a graft polymer obtained from a particulate, highly cross linked diene or alkyl acrylate rubber and graft polymerized alkyl methacylate, acrylonitrile, styrene, alkyl acrylate or mixtures thereof and PA1 (b) 90 to 50 parts by weight of a partly cross-linked, particulate, rubber-like copolymer of acrylonitrile and/or methyl methacrylate and C.sub.1 to C.sub.8 alkyl acrylate having a gel content of from 60 to 99% by weight and an average particle diameter (d.sub.50) of from 0.1 to 0.6 .mu.m, and a process for the preparation of the mixtures and their use for the production of moulded articles.
