Abstract
Polymer compositions derived from selected monoethylenically unsaturated (C -C )carboxylic acid monomers, (C -C )alkyl (meth)acrylate ester monomers and alkoxylated (meth)acrylate monomers used in certain weight ratios to provide enhanced detergent and cleaning performance are disclosed. Polymer compositions containing from 5 to 40% of monoethylenically unsaturated (C -C )carboxylic acid monomer, from 35 to 65% of (C -C )alkyl (meth)acrylate ester monomer and from 20 to 60% of alkoxylated (meth)acrylate monomer provide improved cleaning performance in laundry detergent formulations relative to conventional polymer compositions.
