Abstract

PURPOSE: To obtain a copolymer having excellent ability to disperse a variety of powders in water and being useful as a dispersant, water-treating agent or the like, by hydrolyzing a copolymer comprising a (meth)allylic compound, maleic anhydride and, if necessary, other unsaturated monomers.
CONSTITUTION: A water-soluble copolymer having a unit skeleton of formula IV, wherein R3 is H or CH3, M1 and M2 are each H or an alkali metal, ammonium or amine cation, is produced by hydrolyzing a copolymer comprising (meth)allylic compounds of formulaIor/and II, wherein R1 and R2 are each H or CH3, X1 and X2 are each H or a monocarboxylic acid residue, and X3 is a dicarboxylic acid residue or a group of formula III (e.g., 1-allyloxy-2,3-dihydroxypropane or allyloxymethylethylene carbonate, maleic anhydride and, if necessary, other unsaturated monomers, e.g., (meth)acrylic acid, maleic acid or styrene. This water- soluble copolymer has excellent ability to disperse a variety of powders in water and, particularly, is readily soluble in salt-containing water, free of foaming, useful as a dispersant or a water-treating agent, and is used in paper-sizing agents, wetting agents for paints, etc.
