ABSTRACT:
A laundry detergent composition comprising a surfactant, builder and from about 0.1 to about 25 weight percent, based on the total weight of the laundry detergent composition, of a styrene-anhydride copolymer grafted with polyethylene glycol which is prepared by reacting in a solvent styrene monomer selected from styrene and substituted styrene, with an anhydride monomer selected from maleic anhydride and itaconic anhydride, to form a styrene-anhydride copolymer which is reacted with polyethylene glycol, to form a styrene-anhydride copolymer grafted with polyethylene glycol. The styrene-anhydride copolymers grafted with polyethylene glycol when used in a laundering process, remove soil from fabrics, inhibit soil deposition on fabrics, and provide soil resistance to fabrics.
