Abstract

PURPOSE: To prepare easily handleable polymer beads free of powders, by polymerizing an aqueous solution of a water-soluble vinyl monomer in a dispersion medium in the presence of a dispersion stabilizer which is insoluble to the dispersion medium at room temperature and soluble at the polymerization temperature.
CONSTITUTION: The objective polymer beads are prepared by polymerizing (A) one or more water-soluble vinyl monomers of formulas IWV (R1 is H, methyl; Y is amido group, etc.; Z is alkylene, etc.; M+ is mono-valent cation; R2, R3, R6 are 1W4C alkyl; R4, R5, R7 are 1W4C alkyl, etc.; X-, X'-, X"- are anions) in (B) a dispersion medium comprising a hydrocarbon or a halogenated aromatic hydrocarbon, in the presence of (C) a dispersion stabilizer comprising a cellulose ester or cellulose ether which is insoluble to the dispersion medium at room temperature and soluble at the polymerization temperature, at a temperature of ≥40°C.
