LIVING CATIONIC POLYMERIZATION INITIATOR SYSTEM, AND PRODUCTION METHOD OF POLYMER USING THE SAME

摘要

PROBLEM TO BE SOLVED: To produce a block copolymer of a cationic polymerizable vinyl monomer and a radical polymerizable vinyl monomer.;SOLUTION: Provided is an initiator system that is used for living cationic polymerization of a cationic polymerizable vinyl monomer. A polymer subjected to cationic polymerization is subjected to living radical polymerization of at least one vinyl monomer under a living cationic polymerization initiator that includes: a proton acid (component (A)); and an RAFT cationic agent of the formula (1) (R¹ is a C_1-10 alkyl group that may branch; R² is a C_1-4 alkylene group that may branch; R³ is a substitutable alkyl group, aryl group, arylalkyl group, alkylthio group, arylthio group, arylalkylthio group or acylamino group; Q is O or S; and p is 0, 1 or 2), and under the absence of a metal lewis acid.;COPYRIGHT: (C)2014,JPO&INPIT
