    • 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.
    • 提供一种共聚物组合物,其可以实现在具有高硬度和抗铁沉积能力的水下的粘土分散性之间的高水平的相容性,并且适用于洗涤剂用添加剂和制备该组合物的方法。 本发明的共聚物组合物包含重均分子量为10,000〜50,000的共聚物(P),其含有来自单烯属不饱和二羧酸(或二羧酸酯)单体(a)的结构单元为30〜60 摩尔%,来自单烯属不饱和一元羧酸(或单羧酸酯)单体(b)的结构单元和源自不含酯键的磺酸(或磺酸酯)基团的单体(c)的结构单元和酰胺 键和剩余的单烯属不饱和二羧酸(或二羧酸酯)单体,其含量以酸计小于12,000ppm。
