Abstract

PURPOSE: To obtain a water-soluble copolymer useful as a dispersant for coating compounds, etc., having improved dispersibility, by hydrolyzing a copolymer of an acetal of mono(meth)allyl ether of triol and maleic anhydride.
CONSTITUTION: An acetal of mono(meth)allyl ether of triol (e.g., 2-methyl-4- allyloxymethyl-1,3-dioxolane, etc.) shown by the formula (R1 and R2 are H, methyl; R3 is H, methyl, ethyl; Y1 is triol residue) is copolymerized with (B) maleic anhydride, and, if necessary, (C) other unsaturated monomer[e.g., (meth) acrylic acid, etc.]in a molar ratio of A:B of (1:0.5)W(1:10) in such a way that the total amount of the components A and B is ≥50wt% based on the prepared water-soluble copolymer, to give a copolymer, which is hydrolyzed at 40W180°C, to give the desired water-soluble copolymer having a molecular weight of 500W 100,000.
