Acrylic acid (salt) -maleic acid (salt) copolymer, method for producing the same, and detergent composition |
| abstract |
PROBLEM TO BE SOLVED: To provide an acrylic acid (salt) -maleic acid (salt) copolymer having high clay dispersing ability in high hardness water and high calcium ion trapping ability, a method for producing the same, and a detergent composition I will provide a. SOLUTION: The clay dispersing ability in high hardness water is 50% or more, and the calcium ion trapping ability is 270 mg CaCO 2. 3 / g or more of acrylic acid (salt) -maleic acid (salt) copolymer and an aqueous solvent so that the theoretical solid content concentration of the polymer after polymerization is 40% by weight or more. The amount of acrylic acid (salt) and the amount of maleic acid (salt) used are in the range of 95 to 80/5 to 20 in molar ratio, and (1) persulfate and bisulfite are used as polymerization initiators. And / or (2) a method for producing an acrylic acid (salt) -maleic acid (salt) copolymer which is polymerized by using hydrogen peroxide and a polyvalent metal ion in combination. |
