Claims27
A composition comprised of an aqueous dispersion comprised of:
- (a) a discontinuous phase containing polymer that is comprised predominately of a first cationic water-soluble or water-swellable polymer having at least one first recurring unit of the formula (I),
- wherein R1 is H or CH3, A is O or NH, B is an alkylene or branched alkylene or oxyalkylene group having from 1 to 5 carbons, R2 is a methyl, ethyl, or propyl group, R3 is a methyl, ethyl, or propyl group, R4 is a methyl, ethyl or propyl group, and X is a counterion;
- and (b) a polyamine.
