DISPERSION STABILIZER AND POLYMER PARTICULATE

摘要

PROBLEM TO BE SOLVED: To obtain a dispersion stabilizer for forming polymer particulates without producing an isolated dispersion stabilizer and polymer particulates obtained by using the stabilizer and a polymerization initiator. SOLUTION: A polymerizable monomer is polymerized in a liquid medium containing the dispersion stabilizer of polyvinyl acetal having bonds of an organic group including an azo group or a peroxy group to obtain polymer particles. The production method for the polymer fine particles involves dissolving the polymerizable monomer in a polymerization medium in which the dispersion stabilizer of polyvinyl acetal having bonds of the organic group including the azo group or the peroxy group can be dissolved but the polymer to be produced cannot be dissolved and polymerizing the polymerizable monomer in an inert atmosphere.
