## Abstract

What are described are copolymers obtainable from the free-radical copolymerization at least of the following components: a) cationic monomers selected from the group consisting of cationic (meth)acrylamide monomers and diallyldimethylammonium chloride, b) polyethylene glycol macromonomers, and c) uncharged acrylamide monomers. The copolymers are advantageously suitable, for example, for use in detergent compositions and lead to advantageous shine results, for example, after application on hard surfaces.
