Abstract: 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.

Abstract: Use is claimed as an additive for skin cosmetics or dermatological preparations of a copolymer made by radical initiated copolymerization of a mixture containing an N-vinylimidazole or allylamine monomer, this being followed by partial or full quaternization or protonization should the N-vinylimidazole or allylamine monomer be non- (or only partly) quaternized Use is claimed as an additive for skin cosmetics or dermatological preparations of a copolymer made by radical initiated copolymerization of a composition comprising (by wt.): (a) an N-vinylimidazole or diallylamine (1-99.99%); (b) a neutral or basic water-soluble monomer other than (a) (0-98.99%); (c) an unsaturated acid or anhydride (0-50%); (d) a radically-copolymerisable monomer other than (a), (b) or (c) (0-50%); and (e) a crosslinking monomer with two or more ethylenically-unsaturated non-conjugated double bonds. The copolymerization is followed by partial or full quaternization or protonization should monomer (a) be non- or only partly quaternized.

Abstract: Production of polymers in powder form by radical polymerization of monoethylenically unsaturated carboxylic acids, amides and esters, diallylamines and N-vinyl compounds, in supercritical carbon dioxide is effected by converting carbon dioxide to the supercritical state in a reactor by increasing the pressure to more than 73 bar and adjusting the temperature to 31-100 deg C and adding the reactants.
