    Abstract: The present invention relates to a method for making a copolymer comprising polymerizing the monomers in a solution comprising the monomers and a solvent, wherein the solvent comprises water and an alcohol. Furthermore, the present invention relates to the copolymer obtainable by this method (“the copolymer according to the present invention”) and to the use of the copolymer according to the present invention for styling or for fixing human hair. Furthermore, the present invention relates to the use of a more generally defined copolymer for styling or for fixing human hair, and for providing high gloss to the hair that is styled or fixed.

    Abstract: The invention relates to aqueous polymer dispersions, comprising a water insoluble polymer P in the form of dispersed polymer particles, which is obtainable by free radical aqueous emulsion polymerization of ethylenically unsaturated monomers M, which comprise a) at least one monomer M1 which exhibits two ethylenically unsaturated moieties which are connected by a linker which comprises a disulfide moiety, and b) at least one monoethylenically unsaturated monomer M2, which has a low water solubility. The invention also relates to processes for preparing such an aqueous polymer dispersion, to solid polymer compositions in powder form, obtainable by drying such polymer dispersions, to the use of such polymer dispersions in a coating material, adhesive or sealant and to a methods of coating a surface of a substrate which comprises applying an aqueous coating composition, which contains such an polymer dispersion.

    Abstract: The present invention relates to a polymer comprising repeating units derived from at least one first monomer (monomer A) which is a molecule comprising a thiolactone ring and an ethylenically unsaturated, polymerizable double bond, and at least one second monomer (monomer B) which is N-vinyl pyrrolidone. Furthermore the present invention relates to a modified polymer, the structure of which is identical to the structure of the said polymer apart from the only difference, which is that all or at least some of the thiolactone moieties of the said polymer are modified by opening the thiolactone ring with a substance selected from the group consisting of ammonia, a primary amine, 2-amino-1-ethanol and L-lysine, wherein the N-atom of said substance is binding to the carbonyl group of the opened thiolactone ring. Furthermore, the present invention relates to a process for making the modified polymer and to the use of the polymer or of the modified polymer for treating hair.
