Polymer fine particles manufacturing method

Abstract

A method for manufacturing polymer fine particles having a narrow particle diameter distribution without any particular limitations on the raw materials and the like. To achieve this purpose, this method for manufacturing polymer fine particles includes polymerizing a vinyl monomer using a dispersion polymerization method, wherein the amount of water in the reaction liquid in the polymerizing is no more than 30,000 ppm, the reactor for carrying out the polymerizing is a stirring tank reactor, the stirring blade attached to the stirring rotation shaft of the stirring tank reactor is one type selected from a large wide blade and a large lattice blade, and the tip speed of the stirring blade is no more than 1.0 m/sec.
