摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of polymer particles which prevents the occurrence of aggregated particles and is inhibited in the foaming of the latex of the polymer particles resulting from agitation or transfer. SOLUTION: In the method of manufacturing polymer particles by adding a vinyl monomer, a polymerization initiator soluble in the monomer and a first surfactant in an aqueous medium, starting the polymerization after the emulsification of them and adding a second surfactant after the start of the polymerization, a reactive surfactant is used as the second surfactant. The second surfactant is preferably added between 2 and 50% polymerization conversion ratio of the vinyl monomer. COPYRIGHT: (C)2008,JPO&INPIT
