Abstract: 1. A copolymer obtained by free-radical copolymerization of an alkyl acrylate or methacrylate, a neutral nitrogen-containing water-soluble monomer, a monomer containing cationic groups, and an olefinically unsaturated carboxylic acid of 3 or 4 carbon atoms, characterized in that it is obtained by free-radical copolymerization of a) 20 to 75% by weight of ethyl, n-butyl, tert.-butyl or lauryl acrylate or methacrylate or mixtures thereof, b) 5 to 50% by weight of N-vinylpyrrolidone, N-vinylcaprolactam or mixtures thereof, c) 1 to 25% by weight of N-vinylimidazole, 1-vinyl-2-methylimidazole or mixtures thereof, and d) 1 to 25% by weight of acrylic acid or methacrylic acid, and has a Fikentscher K value of from 15 to 75, measured in ethanol at 25 degrees C.

Abstract: Water-soluble terpolymers which contain, as copolymerized units, (a) from 10 to 35% by weight of an N-vinyllactam or an N-vinyl acid amide, (b) from 5 to 20% by weight of acrylic acid or of a salt of acrylic acid and (c) from 80 to 50% by weight of a C1-C4-alkyl vinyl ether, and have a glass transition temperature Tg below 60 DEG C. can be prepared by polymerizing the monomer mixture in an inert organic solvent in the presence of a polymerization initiator and can, where appropriate, be partially or completely neutralized with a base, so as to form a salt. The products may be used as raw materials for adhesives or, in the form of an aqueous solution, as the adhesive itself.
