Abstract

A molding material from a particulate graft polymer which consists of PA1 A: a grafting base A based on an acrylate rubber and PA1 B: a graft B of PA2 B1: from 40 to 89.9% by weight of at least one vinylaromatic monomer B1 PA2 B2: from 10 to 49.9% by weight of at least one polar, coplymerizable, ethylenically unsaturated monomer B2 PA2 B3: from 0.1 to 20% by weight of at least one monomer B3 containing one or more acidic groups.
