Water-soluble cationic copolymers with hydrolytically-stable quaternized pyrrolidine units and sec. amine units in the polymer chain, used e.g. for antibacterial, antistatic or non-stick treatment of substrates

摘要

Water-soluble cationic copolymers with hydrolytically-stable quaternized pyrrolidine units and sec. amine units in the polymer chain. Water-soluble cationic copolymers of formula (I) with hydrolytically-stable quat. ammonium units (A) and sec. amine units (B). R1 = 1-12C alkyl; R2 = 1-3C alkyl; X = a suitable counter-ion; and a, b = 1-99 mol% based on units in the whole molecule. An Independent claim is also included for a method for the production of (I) by radical copolymerization of a diallyl-dialkyl-ammonium compound with a N-vinyl-N-alkyl-carboxylic acid amide in a solvent, followed by partial or complete hydrolysis.
