Abstract
A method for producing polymer particles includes a suspension step of suspending a first liquid mixture containing an oily olefin monomer and a radical polymerization initiator in a second liquid mixture containing water, an iodide ion, and an iodine molecule, to prepare a suspension in which an oil droplet containing the oily olefin monomer and the radical polymerization initiator is dispersed in the water containing the iodide ion and the iodine molecule, a synthesis step of synthesizing an iodine compound by allowing a radical generated by cleavage of the radical polymerization initiator to react with the iodine molecule in the oil droplet, and a polymerization step of polymerizing the oily olefin monomer in the oil droplet.
