<P>PROBLEM TO BE SOLVED: To provide a method for producing polymer particles in which suspension polymerization and reverse iodine transfer polymerization are combined, and both molecular-weight controllability and a high polymerization conversion rate can be achieved at high level. <P>SOLUTION: The method for producing polymer particles includes: a preparation step for preparing an oily liquid 1 containing an oily olefin monomer, a radical polymerization initiator, and an iodine molecule; a synthesis step for obtaining an oily liquid 2 containing at least an iodine compound produced by a reaction between a radical generated by cleavage of the radical polymerization initiator and the iodine molecule in the oily liquid 1; a suspension step for obtaining an oil droplet of the oily liquid 2 by suspending the oily liquid 2 in water; and a polymerization step for polymerizing the oily olefin monomer in the oil droplet. <P>COPYRIGHT: (C)2013,JPO&INPIT |
