Claim:
1. A polymer mixture comprising a polymeric component of A1 and A2 and/or A3: A1: from 5 to 95% by weight of a copolymer A1 of A11: from 60 to 80% by weight of at least one styrene or styrene derivative A11, A12: from 40 to 20% by weight of at least one ethylenically unsaturated monomer A12 comprising a nitrile group, A13: from 0 to 20% by weight of at least one other, copolymerizable monomer A13; A2: from 5 to 50% by weight of a graft copolymer A2 with median particle size from 90 to 280 nm, of: A21: from 60 to 80% by weight of at least one rubber-like graft base A21 with Tg<0° C. made of A211: from 70 to 99.8% by weight of at least one alkyl acrylate A211, A212: from 0.2 to 0.6% by weight of at least one allyl methacrylate A212, A214: from 0 to 29.9% by weight of at least one other of the following copolymerizable monomers A214 selected from methyl methacrylate, ethyl methacrylate, phenylmaleimide, acrylamide, and vinyl methyl ether, A22: from 20 to 40% by weight of at least one graft shell made of: A221: from 65 to 70% by weight of at least one vinylaromatic monomer A221, A222: from 30 to 35% by weight of at least one polar, copolymerizable unsaturated monomer A222; A3: from 5-50% by weight of a graft copolymer A3 with particle size from 300 to 600 nm, of: A31: from 60 to 80% by weight of at least one rubber-like graft base A31 with Tg<0° C. made of: A311: from 70 to 99.9% by weight of at least one alkyl acrylate A311, A312: from 0.1 to 0.2% by weight of at least one allyl methacrylate A312, A314: from 0 to 29.9% by weight of at least one other of the following copolymerizable monomers A314 selected from methyl methacrylate, ethyl methacrylate, phenylmaleimide, acrylamide, and vinyl methyl ether, A32: from 20 to 40% by weight of at least one graft shell made of: A321: from 65 to 70% by weight of at least one vinylaromatic monomer A321, A322: from 30 to 35% by weight of at least one polar, copolymerizable unsaturated monomer A322, where the total of the proportions of polymer components A1, A2, and/or A3 is 100% by weight of the polymeric component.
