Abstract: An aqueous dispersion of water-soluble polymers obtained by free radical polymerization of ethylenically unsaturated anionic monomers in an aqueous medium in the presence of a stabilizer, wherein the stabilizer comprises: (a) at least one water-soluble polymer selected from the group consisting of a graft polymer of vinyl acetate and/or vinyl propionate on polyethylene glycol, a polyethylene glycol blocked at one or both terminal groups with an alkyl, a carboxyl or an amino group, and a copolymer of alkyl polyalkylene glycol methacrylate and methacrylic acid; and (b) at least one water-soluble polymer selected from the group consisting of a hydrolyzed copolymer of vinyl alkyl ether and maleic anhydride in the form of free carboxyl groups or in the form of salts at least partially neutralized with one or more alkali metal hydroxides or one or more ammonium bases, a cationically modified potato starch, an anionically modified potato starch, a degraded potato starch and maltodextrin.

Abstract: The invention relates to aqueous dispersions of hydrosoluble polymerisates o f ethylenically unsaturated anionic monomers obtainable by monomer radical polymerisation in an aqueous medium in the presence of at least one type of stabiliser characterised in that the polymerisation is carried out in the presence of at least one type of hydrosoluble polymer of the following group s: (a) branched polymerisates of vinyl acetate and/or vinyl propionate on polyethylenglycol, polyethylenglycol closed on one or two sides, by terminal groups comprising alkyl, carboxyl or amino groups, copolymerisate of alkylpolyalkylenglycolacrylates or alkylpolyalkylenglycolmethacrylates and acrylic acid and/or methacrylic acid, polyalkylenglycols, polyethylenglycole closed on one or two sides, by terminal groups comprising alkyl, carboxyl or amino groups; and (b) hydrolysed copolymerisates of vinylalkylethers and maleic anhydride in the form of free carboxyl groups and in the form of salt s neutralised at least partially by alkali metal hydroxides or ammonium basses and/or a starch of a cationically modified potato starch group, cationically modified potato starch, degradable potato and maltodextrin starches which ar e used in the form of stabilisers. A method for producing said aqueous dispersions by monomer radical polymerisation in an aqueous medium in the presence of said hydrosoluble polymerisates of the groups (a) and (b) and th e use of said aqueous dispersions in the form of thickeners for aqueous system s are also disclosed.
