A polymer having the following monomers in polymerized form (in weight %): A) 49-60% of a first monomer which is selected from the group consisting of methyl acrylate, methyl methacrylate, ethyl acrylate, ethyl methacrylate, C3-alkyl acrylate, C3-alkyl methacrylate, C4-alkyl acrylate, C4-alkyl methacrylate and mixtures thereof, B) 30-40% methacrylic acid, C) 4-15% acrylic acid, and D) 0.02-0.30% of a crosslinking agent having at least two allyl moieties, wherein the sum of the amounts of monomers A to D is 100%. A hair styling composition containing the polymer and use of the polymer or of the hair styling composition for styling hair also are disclosed.

Polymer

The invention relates to a polymer suited for modifying the styling performance and the rheology of a cosmetic preparation, a composition thereof, a method of making it as well as the use of said polymer and the composition respectively. The copolymer comprises at least one non-ionic ethylenically unsaturated C1-C4 (meth)acrylate as monomer A; an ethylenically unsaturated monomer B having as hydrogen bond donor an amide group, said ethylenically unsaturated monomer B being an ethylenically unsaturated monomer having a cyclic amide moiety, as monomer B1 and/or, an ethylenically unsaturated monomer having an acyclic amide group, as monomer B2; at least one ethylenically unsaturated carboxylic acid as monomer C; a macromonomer D; optionally at least one cross-linker E; and optionally at least one further monomer F.

Rheology modifying and setting polymer, composition thereof and method for making it

The present invention relates to a method for producing polymers by radically polymerizing a mixture comprising 99.99 to 10% by weight of at least one &#x3b1;,&#x3b2;-ethylenically unsaturated compound with at least one cationogenic and/or cationic group per molecule, 0 to less than 25% by weight of at least one monoethylenically unsaturated amide-group-containing compound different from a) and also 0.01 to 5% by weight of a crosslinker using at least two different water-insoluble initiators.
