Abstract
Copolymers which have K values of from 30 to 50 are obtainable by free radical solution polymerization of A) from 15 to 84.99% by weight of at least one monomer selected from the group consisting of N-vinylpyrrolidone, N-vinylcaprolactam and N-vinylimidazole, B) from 15 to 84.99% by weight of further monoolefinically unsaturated monomers capable of free radical copolymerization and C) from 0.01 to 2% by weight of at least one monomer capable of free radical copolymerization and having at least two non-conjugated olefinic double bonds in alcoholic solution.
Claims6
A copolymer which has a K value of from 30 to 50, obtained by free radical solution polymerization of
- A) from 15 to 84.99% by weight, based on the total amount of components A, B, and C, of at least one monomer selected from the group consisting of N-vinylpyrrolidone, N-vinylcaprolactam and N-vinylimidazole,
- B) from 15 to 84.99% by weight, based on the total amount of components A, B, and C, of at least one monomer selected from the group consisting of the vinyl esters of saturated C.sub.2 -C.sub.24 monocarboxylic acids and the C.sub.1 -C.sub.10 alkyl esters of acrylic or of methacrylic acid, and
- C) from 0.01 to 2% by weight, based on the total amount of components A, B, and C, of at least one monomer capable of free radical copolymerization and having at least two nonconjugated olefinic double bonds;
- in alcoholic solution.
