    • The object of the present invention is to provide a process for producing a high-quality polymer microparticle 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 the inverse suspension polymerization is conducted dividing at least two steps, 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.
    • 本发明的目的是提供一种通过高生产率的反相悬浮聚合制备具有几微米至几十微米数量级的均匀粒子的高质量聚合物微粒的方法,同时保持优异的分散稳定性而不引起颗粒之间的聚集 。 该方法是通过乙烯基单体的反相聚合生产聚合物微粒的方法,其特征在于反相悬浮聚合进行至少两个步骤,将油溶性氧化剂和水溶性还原剂用作 聚合引发剂,并且在加入水溶性还原剂之后进料油溶性氧化剂。
