Abstract

Copolymers are obtainable by polymerizing a monomer composition containing a) 0% to 40% by weight of one or more ethylenically unsaturated ester compounds of the formula (I), b) 10% to 99.9% by weight of one or more ethylenically unsaturated ester compounds of the formula (II), c) 0% to 80% by weight of one or more ethylenically unsaturated ester compounds of the formula (III), d) 0.1% to 30% by weight of one or more ethylenically unsaturated, polar ester compounds of the formula (IV), and e) 0% to 50% by weight of comonomer, based in each case on the total weight of the ethylenically unsaturated monomers.
