Linear, star-shaped or dendrimeric block copolymers composed of 10 to 90% by weight of at least one block of one or more acrylic acid esters with an alcohol having 1 to 8 C atoms and 10 to 90% by weight of at least one block of one or more methacrylic acid esters an alcohol with 1 to 8 carbon atoms, each block having an average molecular weight (number average) from 1000 to 100,000 g / mol, and the quotient M w / M n (weight average / number average) of each block being less than 2, and their mixtures with styrene or acrylic ester copolymers and optionally acrylate rubbers. |
