Abstract
A comb copolymer with a polymer backbone having grafted lateral macromonomer segments, the method of preparing, and the use thereof as a thickener in cosmetics. The polymer backbone is more than 55% and up to 90% molar ATBS, between 1% and 20% molar cationic monomer or monomer of formula (I): CH═C(R)—C(═O)—Y—(CH)m-N(R) (R), where m is between 1 and 4, Y is O or NH, R1 is H or CH, and Rand Rare each a methyl or ethyl radical, and optionally 0.005% to 1% molar of at least one cross-linking monomer with at least two C═C bonds. The lateral macromonomer segments are polymerized from 9% to 30% molar of N-alkyl acrylamide or N,N-dialkyl acrylamide of formula (II): CH═C(R)—C(═O)—N(R) (R), where Ris H or CHand Rand Rare H or a Cto Calkyl radical, with at least one of Ror Rnot being H.
