    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: An ethylene terpolymer wax comprises units derived from ethylene (40-95 wt.%), units derived from at least one anhydride of 4-10C-dicarboxylic acid having ethylenic carbon-carbon double bond (0.1-40 wt.%), and units derived from ester having a molecular weight of up to 20000 g/moles (0.1-40 wt.%). An ethylene terpolymer wax comprises 40-95 wt.% units derived from ethylene, 0.1-40 wt.% units derived from at least one anhydride of 4-10C-dicarboxylic acid having ethylenic carbon-carbon double bond, and 0.1-40 wt.% units derived from ester of formula I having a molecular weight of up to 20000 g/moles. R1 = H, 1-10C alkyl, 3-12C cycloalkyl, or 6-14C aryl (preferably H or Me); R2 = 1-10C alkyl, 3-12C cycloalkyl, or 6-14C aryl (preferably Me) An Independent claim is also included for preparation of ethylene terpolymer wax by polymerizing ethylene, ester (I), and anhydride of 4-10C dicarboxylic acid at 500-4000 bars and 170-300degreesC.
