Abstract:
1. A copolymer for rheological or cosmetic compositions comprising: a) 15 to 60 w % of at least one non-ionic ethylenically unsaturated C1-C4 (meth)acrylate as monomer A; b) 0.1 to 30 w % of an ethylenically unsaturated monomer B having as hydrogen bond donor an amide group, said ethylenically unsaturated monomer B being c) 30 to 60 w % of at least one ethylenically unsaturated carboxylic acid as monomer C selected from the group consisting of methacrylic acid, acrylic acid and itaconic acid with methacrylic acid making 80 to 100 w % of said monomer C; d) 0.1 to 10 w % of a macromonomer D; e) 0 to 0.3 w % of at least one cross-linker E; f) 0 to 30 w % of at least one further monomer F selected from the group consisting of ethylenically unsaturated cationogenic or cationic monomers and ethylenically unsaturated sulfonic- or phosphonic acids; the sum of the compounds A to F equals 100 w %, with monomer B1 making from ⅙ to 3.45 times the weight amount of the macromonomer D, and/or the weight amount of the monomer B2 being at least three times higher than the weight amount of the macromonomer D; wherein macromonomer D comprises, an ethylenically unsaturated oxyalkylated monomer having the general formula (I): with: R′ representing a hydrophobic moiety selected from linear or branched alkyl, alkylaryl or arylalkyl radicals.
