Abstract
A novel polymer composition comprising the reaction product of: PA1 (a) between about 75 and about 99.9 weight percent of a monocarboxylic acid or salt monomer; PA1 (b) between about 0 and about 25 weight percent of a dicarboxylic acid, anhydride or salt monomer; and PA1 (c) between about 0.1 and about 5.0 weight percent of an acrylic monomer which contains one or more sulfoalkyl groups, where alkyl represents an alkyl moiety containing between 1 and 6 carbon atoms or salt thereof; the sum of the weight percents of (a), (b) and (c) being 100 percent is provided. The polymer demonstrates excellent soil redeposition properties and is particularly useful as a detergent builder.
