摘要：
A particulate graft polymer comprisingA: from 30 to 80% by weight of one or more elastomeric polymers A having a mean particle size of from 30 to 1000 run, comprising, based on A,A1: from 85 to 99.8% by weight of one or more alkyl acrylates A1 having from 1 to 8 carbon atoms in the alkyl radical,A2: from 0.1 to 5% by weight of one or more polyfunctional, crosslinking monomers A2, andA3: from 0.1 to 10% by weight of one or more monomers A3 containing one or more acid groups, orA11: up to 100% by weight of a diene A11,A12: up to 50% by weight of one or more vinyl-aromatic monomers A12,A13: up to 10% by weight of one or more monomers A13 containing one or more acid groups, as the graft base, andB: from 20 to 70% by weight of a shell B grafted onto the elastomeric polymer A and comprising, based on B,B1: from 50 to 89.9% by weight of one or more vinylaromatic monomers B1,B2: from 10 to 49.9% by weight of one or more polar, copolymerizable, ethylenically unsaturated monomers B2, andB3: from 0.1 to 10% by weight of one or more monomers B3 containing one or more basic groups.
