Abstract
Official abstract text for this publication.
A method for producing polymer particles includes a suspension step of suspending a first liquid mixture containing an oily olefin monomer, a radical polymerization initiator, and an iodine molecule in a second liquid mixture containing water and an iodide ion to prepare a suspension containing an oil droplet having the first liquid mixture; 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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for producing polymer particles, comprising: a suspension step of suspending a first liquid mixture containing an oily olefin monomer, a radical polymerization initiator, and an iodine molecule in a second liquid mixture containing water and an iodide ion to prepare a suspension containing an oil droplet comprising the first liquid mixture; a synthesis step of synthesizing an iodine compound by allowing a radical generated by cleavage of the radic…
