Abstract

PURPOSE: To obtain a copolymer having two types of blocks differing in property, and being useful as a dispersant for pigments, a detergent builder or the like, by copolymerizing a polyethylene glycol monoalkyl ether with a (meth)acrylic acid type monomer.
CONSTITUTION: A block copolymer consisting of repeating units (A) of formula III and repeating units (B) of formula IV, and having a weight ratio of total units A to total units B, of 5:95W60:40, is prepared by copolymerizing a polyethylene glycol monoalkyl ether of formula I, wherein n is 5W100, with a (meth)acrylic acid monomer of formula II, wherein R1 is H or CH3 and X is H, a monovalent metal, a bivalent metal, NH4 or an organic amine, in the presence of a polymerization initiator and optionally, neutralizing the product. The copolymer thus prepared is a copolymer which has in the molecule, two types of blocks differing in property, i.e., an anion block containing a carboxyl group and/or a salt thereof and a nonionic and hydrophilic block containing an ethylene oxide high-molar adduct, and which is useful as a dispersant for pigments, a chelating agent, a detergent builder or the like.
