Document Type and Number:
Japanese Patent JP2007533768
Kind Code:
A
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.
