Abstract:
A cationically stabilized emulsion polymer comprising at least one polymerizable monomer which is uncharged or positively charged in an aqueous solution having a pH between 1 and 8, polymerized in the presence of at least one water-soluble polymer having a number-average molecular weight greater than 5000 which comprises a moiety selected from the group consisting of primary amines, secondary amines, tertiary amines and quaternary ammonium salts, with less than 5 weight percent of the monomer units in the water-soluble polymer being comprised of copolymeric units derived from at least one member selected from the group consisting of carbohydrates, modified carbohydrates, polyamide-polyamine epichlorohydrin, and units having the following formula: wherein R1 is selected from the group consisting of H, C1 to C6 alkyl, and C1 to C6 acyl and R2 is selected from the group consisting of H, C1 to C6 alkyl, and the reaction product of epichlorohydrin with polyamides containing the following recurring groups:â€”NH(CnH2nHN)xâ€”COR3COâ€”where n and x are each 2 or more and R3 is a divalent organic radical of a dicarboxylic acid.
