摘要： A (meth)acrylic acid polymer is obtained by conducting a polymerization reaction using 60 mol % or more of a hydrophilic monomer containing (meth)acrylic acid and a combination of at least one kind of persulfate salts and at least one kind of bisulfite salts as an initiator series under conditions that a pH is smaller than 5 and a degree of neutralization is smaller than 40 mol %, in such a manner that a solid concentration when the polymerization reaction ends is 40% or higher. The resulting polymer has a weight average molecular weight ranging from 3,000 to 15,000, a sulfonic acid group at an end terminal, and an anti-gelling ability Q-value smaller than 2.0, where the anti-gelling ability Q-value is defined as: Q = degree of gelling × 10 5 weight average molecular weigh ⁢ t . Consequently, it has become possible to provide a low-molecular-weight (meth)acrylic acid polymer having not only excellent dispersing ability and chleating ability, but also high resistance to gelling, and an efficient manufacturing method of such a polymer.

摘要： 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. Such detergent builder has improved angle of repose, fluidity, and hygroscopicity, and the detergent builder having the described properties can be prepared by the dry-mixing process, thereby permitting the detergent composition having described excellent properties to be manufactured at low cost.
