ABSTRACT:
Use of a copolymer (A) preparable by free-radical polymerization ofa) at least one olefinically unsaturated monomer andb) at least one olefinically unsaturated monomer different than the olefinically unsaturated monomer (a) and of the general formula Iin-line-formulae description="In-line Formulae" end="lead"?R1R2C═CR3R4 (I),in-line-formulae description="In-line Formulae" end="tail"?in which the radicals R1, R2, R3and R4, in each case independently of one another, are hydrogen atoms or substituted or unsubstituted alkyl, cycloalkyl, alkylcycloalkyl, cycloalkylalkyl, aryl, alkylaryl, cycloalkylaryl, arylalkyl or arylcycloalkyl radicals, with the proviso that at least two of the variables R1, R2, R3and R4are substituted or unsubstituted aryl, arylalkyl or arylcycloalkyl radicals, especially substituted or unsubstituted aryl radicals;in an aqueous medium for producing molding compounds and moldings.
