Wasserloesliche ionische Copolymere

Die Erfindung betrifft wasserloesliche ionische Copolymere aus hydrolysestabilen quaternaeren Ammoniumeinheiten sowie sekundaeren Amineinheiten und gegebenenfalls am Stickstoff substituierte Carbonsaeureamideinheiten. Erhalten werden diese durch eine Copolymerisation eine Diallyldialkylammoniumverbindung mit einem N-Vinyl-N-Alkylcarbonsaeureamid und anschliessende Total- oder Partialhydrolyse. Die sekundaere Amineinheit ermoeglicht die kovalente Kopplung der Copolymere an geeignete reaktive bzw. aktivierte Oberflaechen.

DE 10211561 A UPAB: 20040226 NOVELTY - Water-soluble cationic copolymers with hydrolytically-stable quaternized pyrrolidine units and sec. amine units in the polymer chain. DETAILED DESCRIPTION - 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. USE - For coating surfaces, for the antibacterial treatment of substrates, for the antistatic treatment of substrates and as a non-stick treatment for substrates (claimed). ADVANTAGE - New cationic polymers which can be permanently coupled to reactive surfaces to provide a durable cationic finish.
