Abstract: A polymer which containsfrom 50 to 99.98% by weight of a C1-C12 alkyl (meth)acrylate a),from 0.02 to 10% by weight of a vinylaromatic compound b),from 0 to 10% by weight of an ethylenically unsaturated acid or of an ethylenically unsaturated acid anhydride c), andfrom 0 to 40% by weight of further monomers d), the percentages by weight being based on the polymer and the polymer being obtainable by polymerizing the monomers a) to d) in at least two stages which differ in their content of vinylaromatic compounds in such a way that the content of vinylaromatic compounds in the vinylaromatics-rich stage is at least 5 times as great as in the low-vinylaromatics stage.
