Abstract

A polymer which is composed of PA1 from 50 to 99.98% by weight of a C.sub.1 -C.sub.12 alkyl (meth)acrylate a), PA1 from 0.02 to 1.8% by weight of a vinyl-aromatic compound b), PA1 from 0 to 10% by weight of an ethylenically unsaturated acid or an ethylenically unsaturated acid anhydride c), and PA1 from 0 to 40% by weight of other monomers d), the percentages by weight being based on the polymer.
