摘要

Polycarboxylate additives suitable for use in automatic dishwasher detergent compositions are prepared by polymerizing three or more monomers including monoethylenically unsaturated C3 to C6 monocarboxylic acids such as acrylic acid, monoethylenically unsaturated C4 to C6 dicarboxylic acids such as maleic acid, and monoethylenically unsaturated esters of acrylic or methacrylic acid. Automatic dishwasher detergents prepared from these additives produce low filming and spotting on washed glassware.
