Beschreibung
Zusammenfassung:	Process for the preparation of polymers of vinylphosphonic acid in water with the aid of catalysts which form free radicals, which comprises heating vinylphosphonic acid and (meth)acrylic acid to temperatures of 40 DEG to 120 DEG C. in water in the presence of 1 to 5.5% by weight of aliphatic peroxy esters and/or diacyl peroxides which dissociate by half in one hour at temperatures below 122 DEG C., the total amount of vinylphosphonic acid being taken together with up to 30% by weight, based on the total amount of monomer, of (meth)acrylic acid and the remainder of the (meth)acrylic acid being added in the course of the reaction. The copolymers are suitable for use in detergent and cleaning agents.
