Kationische amphiphile Assoziativpolymere, Verfahren zur Herstellung, Verwendung als Verdickungsmittel und Zusammensetzung

摘要

quaternarized amino-functional polymers (I) are new. Polymers of formula (I) are new: R, R' = H or hydrophobic groups; X, X' = groups comprising a tertiary or quaternary amine function optionally bearing a hydrophobic group; L, L' = groups derived from a diisocyanate; Y = a hydrophilic group; r = 1-100; m = 1-1000; The polymer contains at least one protonated or quaternarized amine function and at least one hydrophobic group and at least 85% of the amine functions are quaternarized. Independent claims are also included for: (1) production of (I) by reacting a quaternarized amine derivative with a diisocyanate prepolymer; (2) a composition comprising (I).
