Ethylene terpolymer waxes, their preparation and their use

The invention relates to the use of at least one copolymer obtainable by

Use of crosslinked cationic polymers in skin cosmetic and dermatological preparations

An aqueous polymer dispersion prepared by free-radical polymerization of vinyl acetate in the presence of at least one ionic emulsifier, at least one free-radical initiator and at least one protective colloid, wherein the polymerization is carried out in the presence of a polymerization regulator and wherein the ratio by weight of protective colloid to ionic emulsifier is at least 4:1 and wherein the ratio by weight of vinyl acetate monomer to protective colloid is between 19:1 and 4:1.

Aqueous polymer dispersion

The invention relates to a method for producing thixotropic agents containing 0.1&#x2013;30 wt.-% of at least one ethylene terpolymer wax, 5&#x2013;7 wt.-% of at least one solvent, which is incompatible with the ethylene terpolymer wax, 5&#x2013;85 wt.-% of of at least one solvent which is compatible with the ethylene terpolymer wax and with one or more of the first-named solvents.

Thixotropic agents comprising ethylene terpolymer waxes

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&#xb0; 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&#xb0; 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.

Acrylate polymers based on tert-butyl acrylate and/or tert-butyl methacrylate

Interpolymer of a polymer of unsaturated olefinically monomers without carboxylic groups and a polymeric surface active agent.

Interpolymers

A process for the preparation of pulverulent, cationic, crosslinked polymers based on monoethylenically unsaturated monomers containing a quaternized or quaternizable nitrogen atom comprises carrying out the polymerization in supercritical carbon dioxide as inert diluent with mixing at from 31&deg; C. to 150&deg; C. and above 73 bar.
