Abstract
A method for producing polymer particles includes a preparation step for preparing a first oily liquid containing an oily olefin monomer, a radical polymerization initiator, and an iodine molecule, a synthesis step for obtaining a second oily liquid 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 first oily liquid, a suspension step for obtaining an oil droplet of the second oily liquid by suspending the second oily liquid in water, and a polymerization step for polymerizing the oily olefin monomer in the oil droplet.
Claims5
A method for producing polymer particles, comprising:
- a step comprising preparing a first oily liquid by dissolving a radical polymerization initiator and an iodine molecule in an oily olefin monomer;
- a step comprising obtaining a second oily liquid by heating the first oily liquid to synthesize iodine compounds, wherein the second oily liquid has a viscosity of 50 mPa·s or less;
- a suspension step comprising suspending the second oily liquid in water;
- and
- a polymerization step comprising polymerizing the oily olefin monomer in the second oily liquid.
