Patent number: 5962401Abstract: A detergent builder is composed of a maleic acid copolymer having a weight-average molecular weight in a range of from 5,000 to 100,000, wherein a molar ratio of a maleic acid (salt) monomer to total monomers used in a process is in a range of from 0.1 to 0.9. The detergent builder is obtained by a copolymerization reaction of the monomers using a hydrogen peroxide and a persulfate as a polymerization initiator. As such detergent builder has high calcium ion stability constant and desirable property against iron particle deposition, it is suitably used as a detergent composition. The detergent builder may be prepared by granulation with agitation of powders containing the maleic acid copolymer as water-soluble polycarboxylic acid (salt) using a surface active agent.Type: GrantFiled: July 16, 1996Date of Patent: October 5, 1999Assignee: Nippon Shokubai Co., Ltd.Inventors: Shigeru Yamaguchi, Yoshihiro Maeda
