Abstract:
1. An acrylate polymer with a K value of from 10 to 60, obtained by free-radical polymerization of 30 to 99% by weight of tert-butyl acrylate and/or tert-butyl methacrylate as monomer A, 1 to 28% by weight of acrylic acid and/or methacrylic acid as monomer B and 0 to 60% by weight of a free-radically copolymerizable monomer or a free-radically copolymerizable monomer mixture as monomer C, where at least one of the monomers C produces a homopolymer with a glass transition temperature of less than 30° C., with the proviso that the % by weight add up to 100, in the presence of alkanethiols with a carbon chain length of from C 10 to C 22 and subsequent hydrogen peroxide treatment. and subsequent hydrogen peroxide treatment.
