AUTOMATIC DISHWASHING COMPOSITION CONTAINING A SULFONATED COPOLYMER |
摘要 |
<p>An automatic dishwashing composition comprising a builder and a water-soluble copolymer which comprises: (a) from about 30 to 60 mol% of the copolymer having a structural unit originating from a monoethylenic unsaturated dicarboxylic acid (or dicarboxylate) monomer having 4 to 6 carbon atoms or its anhydride at; (b) from about 30 to 60 mol% of the copolymer having a structural unit originating from a monoethylenic unsaturated monocarboxylic acid (or monocarboxylate) monomer having 3 to 8 carbon atoms; and(c) from about 5 to 15 mol% of the polymer having a structural unit originating from a monoethylenic unsaturated monomer having a sulfonic (or sulfonate) group; wherein the water-soluble copolymer has a weight average molecular weight of from about 1,000 to about 50,000 wherein the copolymer is polymerized with hydrogen peroxide.</p> |
