Abstract

Particulate elastomeric graft polymers which are suitable for improving the quality of macromolecular base materials B consist of PA1 a) a grafting core comprising an elastomeric polymer P.sub.K, the particles having a mean particle diameter of from 1 to 150 .mu.m, and PA1 b) one or more shells, the outer shell S.sub.a consisting of a polymer P.sub.a which is compatible or partly compatible with the base material B.
