CA 2333245
Emulsions are disclosed which contain (a) an aqueous carrier and (b) a polymer mixture of (1) 40-99.5 % by weight of a copolymer with a weight average molecular weight of at least 3000; and (2) 0.5-60 % by weight of a stabilizing copolymer dispersed in water, wherein the stabilizing copolymer comprises a structured polymer having a hydrophobic portion and a hydrophilic portion, wherein said structured polymer is selected from the group consisting of (i) polymers comprising 5-95% by weight of a hydrophilic macromonomer having at least 10% of an acid functional monomer and 5-95% by weight of at least one hydrophobic monomer polymerized in the presence of the macromonomer; and (ii) polymers comprising 5-95% by weight of a hydrophobic macromonomer and 5-95% by weight of hydrophilic copolymer comprising at least 10%,of an acid functional monomer polymerized in the presence of the macromonomer.
