Procedure

Copolymer of 1-vinylimidazole and 1-vinylpyrrolidone in the molar ratio 55:45 which was quaternized by reaction with dimethyl sulfate to give a terpolymer with units of 1-vinylimidazole, 1-vinyl-3-methylimidazolinium methosulfate and 1-vinylpyrrolidone in the molar ratio 45:10:45. The quaternary polymer had a K value of 34.7.
