摘要： An industrially advantageous process for producing a crosslinked polymer containing carboxyl groups comprises (a) polymerizing an α,β-unsaturated carboxylic acid and a crosslinking agent copolymerizable with it in the presence of a radical polymerization catalyst in an inert solvent, (b) heating the polymerized product in the presence of a radical scavenger and (c) removing the solvent. The polymer dissolved in water has high viscosity and excellent flowing properties.
