Abstract:
A polymer produced by reacting:a) from 50 to 99.98% by weight of a C1-C2 alkyl (meth)acrylate; b) from 0.02 to 10% by weight of a vinyl aromatic compound; c) from 0 to 10% by weight of an ethylenically unsaturated acid or of an ethylenically unsaturated acid anhydride; and d) from 0 to 40% by weight of other monomers, the percentages by weight being based on the polymer and the polymer being obtained by polymerizing the monomers a)-d) in at least two stages which differ in their content of vinyl aromatic compounds such that the content of vinyl aromatic compounds in a vinyl aromatic-rich stage is at least five times as great as in a low-vinyl aromatic stage, wherein the polymer has a peel strength of at least 17.2 N/2 cm.
