A low color or colorless polymaleate as determined by a Gardner color number of 8 or less, said polymaleate is prepared by aqueous solution polymerization of 70 to 99.9 weight percent of maleic acid, 0.1 to 30 weight percent of an allylic sulfonate monomer, and 0.5 to 50 µmoles, based on the moles of monomer, of a polyvalent transition metal ion selected from group consisting of Group IVA, VA, VIA, VIIA, VIIIA, IB, IIB, and combinations thereof, wherein the weight percents are based on the total weight of monomer, provided that 10 to 60 mole percent of the carboxylic acid groups on the maleic acid are neutralized prior to polymerization. The low color or colorless polymaleates provide permanent press properties to textiles treated therewith and increases the resistance of such textiles to laundering abrasion. The polymaleates also may be used in cleaning compositions to disperse and suspend soils.
