Disclosed is a method for polymerizing a monomer in a liquid phase dispersed in a continuous liquid phase (dispersed phase polymerization) using a stabilizer for the dispersed phase known as a reaction stabilizer. RbRcC = CX1X2 (X1 is F or Cl; X2 is H, F or Cl; Rb and Rc are each independently -H, Cl, F or -preferably chlorinated and / or fluorinated or more A dispersion phase polymerization method of a halogenated vinyl compound having a advantageously perchlorinated or perfluorinated alkyl group), wherein the monomer comprises one or more free radical sources and a polymer chain and a thiocarbonylthio group [S ( C = S)] is introduced into the aqueous phase together with one or more reaction stabilizers, and a redox polymerization initiator is used to carry out dispersed phase polymerization at less than 40 ° C., preferably 30 ° C. or less. The method wherein the polymer chain comprises non- (N-vinyl lactam) monomer units. [Selection figure] None |
