WATER-SOLUBLE COPOLYMERS AND THEIR PREPARATION

摘要

Water-soluble polymers having K values of from 5 to 100 (determined on the Na salt of the polymers according to H. Fikentscher in aqueous solution at 25.degree.C, a pH of 7 and a concentration of 1% by weight of the Na salt of the polymer) are prepared by polymerizing a monomer mixture of (a) monoethylenically unsaturated C3-C5-monocarboxylic acids and (b) more than 20-100 mol % of monomers which have two or more ethylenically unsaturated double bonds linked via one or more ester or amide functions and which contain one or more -CO-OX groups, where X is one hydrogen equivalent, one alkali metal equivalent or one alkaline earth metal equivalent or an ammonium group, in aqueous solution in the presence of a polymerization initiator, and the polymers are used in amounts of from 0.5 to 25% by weight in detergents and cleaners.
