摘要： The object of the present invention is to provide a process for producing high-quality polymer microparticles having uniform particle size of the order of several micrometers to tens of micrometers by inverse suspension polymerization at high productivity while keeping excellent dispersion stability without causing aggregation among particles. The process is one for the production of polymer microparticles by inverse polymerization of a vinyl monomer and is characterized in that an oil-soluble oxidizing agent and a water-soluble reducing agent are used as a polymerization initiator and the oil-soluble oxidizing agent is fed after the water-soluble reducing agent is fed.

摘要： The object of the present invention is to provide a process for producing high-quality polymer microparticles having uniform particle size of the order of several micrometers to tens of micrometers by inverse suspension polymerization at high productivity while keeping excellent dispersion stability without causing aggregation among particles. The process is one for the production of polymer microparticles by inverse suspension polymerization of a vinyl monomer and includes steps of preparing in a dispersing tank a water-in-oil (W/O) type emulsion in which an organic solvent is a continuous phase and an aqueous solution of a vinyl-based monomer is a dispersing phase, and conducting the inverse suspension polymerization while feeding the water-in-oil (W/O) type emulsion to a continuous stirred tank reactor.
