Abstract:
1. An aqueous composition comprising: a polymer comprising as polymerized units, based on the total weight of said polymer: a) from greater than 7.5 to less than 100 weight % of at least one ionic monomer, and b) from greater than 0 to less than 92.5 weight % of a nonionic surfactant monomer; wherein said polymer is formed by an aqueous free radical polymerization process in the presence of 0.01 to 1 weight %, based on the total weight of said polymer, of an organic compound selected from the group consisting of t-alkyl hydroperoxides, t-alkyl peroxides, t-alkyl peresters, and mixtures thereof, wherein said t-alkyl group has at least 5 carbon atoms.
