  • Publication number: 20110230612
    Abstract: There is provided a method of forming an aqueous composition, said method comprising (a) first, forming at least one aqueous polymer dispersion by a process comprising polymerizing a monomer mix comprising 5-50% by weight based on the weight of said monomer mix, of one or more carboxylic acid functional monomers; (b) second, adding to said aqueous polymer dispersion, ingredients comprising (i) 1 to 10 parts by weight of at least one swelling agent, based on 100 parts by weight of said monomer mix; and (ii) one or more nonionic surfactant, anionic surfactant, or mixture thereof; and (c) third, adding calcium cation or magnesium cation or a mixture thereof to said aqueous polymer dispersion.
