Abstract

PURPOSE: To obtain a water-soluble gelatinous product, showing a high viscosity at a low concentration, and having a high yield value, by crosskinking a specific copolymer having carboxyl groups and glycidyl groups.
CONSTITUTION: (A) 50wt% or more α,β-unsaturated carboxylic acid monomer, e.g. acrylicacid acid, (B) 0.05W10wt% polymerizable monomer having a glycidyl group, e.g. glycidyl, methacrylate, (C) 0W40wt% polymerizable monomer copolymerizable with the monomer in the component (B), e.g. methyl acrylate, and an organic radical catalyst are dissolved in an inert solvent, e.g. hexane, capable of dissolving the respective monomers but undissolving the formed copolymer at 30W90°C, and the resultant copolymer is then heat-treated at 50W160°C.
USE: Viscosity increasing, gelling and dispersing agents, etc.
