摘要： Graft copolymers providing soil release benefits in laundry detergent compositions contain backbone units derived from an ethylenically unsaturated monomer, hydrophilic uncharged side chains, and cationically chargeable or charged side chains containing a tertiary or quaternary nitrogen atom. Preferred copolymers have a methacrylate backbone with polyethylene oxide and 2-dimethylaminoethyl methacrylate (DMAEMA) side chains. The graft copolymers may be prepared by radical polymerisation.

摘要： Hydrophobically modified vinyl pyrrolidone polymers which are copolymers having a vinyl pyrrolidone backbone and pendant hydrophobic side chains are useful in laundry detergent compositions to improve detergency and/or antiredeposition. The pendant hydrophobic side chains preferably comprise alkyl chains containing from 4 to 20 carbon atoms and may be linked to the backbone via an ester linkage.
