摘要：A particulate graft polymer comprising A: a graft base A based on an acrylaterubber A1 comprising A11: from 75 to 99.8 % by weight of at least one alkyl acrylate A11having 1-8 carbon atoms in the alkyl radical, A12: from 0.1 to 5 % by weight of at leastone polyfunctional, crosslinking-effecting monomer A12 A13: from 0.1 to 20 % by weightof at least one monomer A13 containing one or more basic groups, or based on a dienerubber A2 comprising A21: at least 50 % by weight of one or more dienes A21 A22: up to50 % by weight of at least one copolymerisable, ethylenically unsaturated monomer A22,A23: from 0.1 to 15 % by weight of at least one monomer A23 containing one or morebasic groups, and B: a graft shell B comprising B1: from 40 to .9 % by weight of at leastone vinylaromatic monomer B1, B2: from 10 to 49.9 % by weight of at least one polar,copolymerisable, ethylenically unsaturated monomer B2, and B3: from 0.1 to 20 % byweight of at least one monomer B3 containing one or more acidic groups. b
