摘要：The invention relates to acrylate polymers comprising a K-value ranging from10 to 60, which can be obtained by the radical polymerization of: 30 to 99 wt. % of tert-butyl acrylate and/or tert-butyl methacrylate designated as monomer A; 1 to 28 wt. % ofacrylic acid and/or methacrylic acid designated as monomer B, and; 0 to 60 wt. % of aradically copolymerizable monomer or of a radically copolymerizable monomer mixturedesignated as monomer C, whereby at least one of monomers C yields a homopolymerwith a glass-transition temperature lower than 30° C., with the provision that the wt. %'stotal 100. The radical polymerization is carried out in the presence of alkane thiols with aC chain length of C 14 to C 22. The invention also relates to acrylate polymers comprisinga K-value ranging from 10 to 60, which can be obtained by the radical polymerization of:30 to 99 wt. % of tert-butyl acrylate and/or tert-butyl methacrylate designated asmonomer A; 1 to 28 wt. % of acrylic acid and/or methacrylic acid designated as monomerB, and; 0 to 60 wt. % of a radically copolymerizable monomer or of a radically

copolymerizable monomer mixture designated as monomer C, whereby at least one of

monomers C yields a homopolymer with a glass-transition temperature lower than 30° C.,with the provision that the wt. %'s total 100. The radical polymerization is carried out inthe presence of alkane thiols with a C chain length of C 10 to C 22 followed by ahydrogen peroxide treatment. The invention also relates to the use of these acrylatepolymers as film formers as well as to their use in cosmetic preparations.
