    摘要： The invention relates to acrylate polymers comprising a 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 as monomer A; 1 to 28 wt. % of acrylic acid and/or methacrylic acid designated as monomer B, 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 in the presence of alkane thiols with a C chain length of C 14 to C 22. The invention also relates to acrylate polymers comprising a 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 as monomer A; 1 to 28 wt. % of acrylic acid and/or methacrylic acid designated as monomer B, 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 in the presence of alkane thiols with a C chain length of C 10 to C 22 followed by a hydrogen peroxide treatment. The invention also relates to the use of these acrylate polymers as film formers as well as to their use in cosmetic preparations.

    摘要： The invention relates to fixative agents for hair containing: A) between 0.5 and 20 wt. % of a homopolymer of N-vinylcaprolactam or of an anionic or non-ionic copolymer consisting of at least 70 wt. % of N-vinylcaprolactam (polymer A); and B) between 0.5 and 20 wt. % of a terpolymer (polymer B), obtained by the copolymerisation of (a) at least one C1-C4 N-alkylacrylamide or a C1-C4 N-alkylmethacrylamide and (b) at least one C1-C4 hydroxyalkyl ester or a C1-C4 alkyl ester of acrylic acid or methacrylic acid and (c) acrylic acid and/or methacrylic acid, C) between 0.5 and 20 wt. % of a polymer, selected from the group of copolymers consisting of vinylpyrrolidone and a vinyl ester and homopolymers of vinylpyrrolidone.
