<p>PROBLEM TO BE SOLVED: To provide a method for producing polymer particles by combining suspension polymerization and reverse iodine transfer polymerization, which can satisfy both of molecular weight controllability and polymerization conversion at a high level.SOLUTION: The method for producing polymer particles comprises: a suspension step in which a first mixed liquid containing oily olefin monomers and a radical polymerization initiator is suspended in a second mixed liquid containing water, iodide ions and iodine molecules to obtain a suspension liquid in which oil droplets containing the oily olefin monomers and the radical polymerization initiator are dispersed; a synthesis step in which radicals produced by the cleavage of the radical polymerization initiator in the oil droplets and the iodine molecules are reacted to synthesize an iodine compound; and a polymerization step in which the oily olefin monomers in the oil droplets are polymerized.</p> |
