    • The invention relates to multifunctional polymers, comprising polymerised units of (a) ?-acyloxyacrylonitrile, ?-haloacrylic acid, ?-acyloxyacrylate ester and/or ?-hydroxyacrylic acid; (b) monoethylenic unsaturated carboxylic acids; (c) vinyl esters of saturated aliphatic monocarboxylic acids and/or vinyl alcohol and, optionally, (d) other monoethylenic unsaturated monomers, co-polymerisable with the monomers (a) to (c) and, optionally, (e) at least two cross-linking compounds, containing ethylenic unsaturated double bonds and with a K-value of at least 7 (determined by the method of H. Fikentscher in acetone at 25?o¿C and a polymer concentration of 1 % by weight). The invention further relates to a method for the production of multifunctional polymers by the copolymerisation of monomer mixtures comprising (a) ?-acyloxyacrylonitrile, ?-haloacrylic acid, ?-acyloxyacrylate ester and/or ?-hydroxyacrylic acid; (b) monoethylenic unsaturated carboxylic acids; (c) vinyl esters of saturated aliphatic monocarboxylic acids and/or vinyl alcohol and, optionally (d) other monoethylenic unsaturated monomers, co-polymerisable with the monomers (a) to (c) and, optionally, (e) at least two cross-linking compounds, containing ethylenic unsaturated double bonds, in the presence of radical forming polymerisation initiators and partial or complete hydrolysis of polymerised monomer units (a) and (c) in the co-polymer obtained as above. Furthermore, the invention relates to the use of said multifunctional copolymers as additives in washing and cleaning agents, for the binding of polyvalent metal ions, as stabiliser in the bleaching of textiles and the bleaching of fibrous material for the production of paper.
