Document Type and Number:
Japanese Patent JP2011503246
Kind Code:
A
Abstract:
Provided are a copolymer composition which can achieve a high level of compatibility between clay dispersibility under water having high hardness and an anti-iron deposition ability and is suitable for an additive for a detergent, and a method of producing the composition. The copolymer composition of the present invention includes a copolymer (P) which has a weight average molecular weight of 10,000 to 50,000 and contains a structural unit originating from a monoethylenic unsaturated dicarboxylic acid (or dicarboxylate) monomer (a) at 30 to 60 mol %, a structural unit originating from a monoethylenic unsaturated monocarboxylic acid (or monocarboxylate) monomer (b), and a structural unit originating from a sulfonic acid (or sulfonate) group-containing monomer (c) free of an ester bond and an amide bond, and a remaining monoethylenic unsaturated dicarboxylic acid (or dicarboxylate) monomer a content of which in terms of an acid is less than 12,000 ppm.
