Abstract:
1. A thickener comprising i) at least one cationic polymer preparable by polymerization of ii) at least one activator, where the ratio of activator to cationic polymer is 10.5:100 to 50:100 [% by weight/% by weight]; wherein the at least one cationic monomer according to component a) in the cationic polymer is selected from a compound of the formula (II) where R R R R X is —O— or —NH— and Y is Cl; Br; I; hydrogensulfate or methosulfate; wherein the nonionic monomer according to component a) in the cationic polymer is selected from N-vinylpyrrolidone, N-vinylimidazole or a compound of the formula (III) where R R R wherein the at least one ethylenically unsaturated associative monomer according to component b) in the cationic polymer is selected from a compound of the formula (I) where R is C R′ is H or C R″ is H or methyl, n is an integer from 0 to 100; wherein the crosslinker (component c)) in the cationic polymer is selected from divinylbenzene; tetraallylammonium chloride; allyl acrylates; allyl methacrylates; diacrylates and dimethacrylates of glycols or polyglycols; butadiene; 1,7-octadiene, allylacrylamides or allylmethacrylamides; bisacrylamidoacetic acid; N,N′-methylenebisacrylamide, or polyol polyallyl ethers; polyallyl sucrose or pentaerythritol triallyl ether; wherein the chain transfer agent (component d) in the cationic polymer is selected from the group consisting of mercaptans, lactic acid, formic acid, isopropanol, hypophosphites, and combinations thereof; and wherein the activator is selected from the group consisting of fatty alcohol alcoxylates, alkyl glycosides, alkyl carboxylates, alkylbenzenesulfonates, secondary alkanesulfonates, fatty alcohol sulfates, and combinations thereof.
