METHOD FOR PRODUCING VINYL-BASED POLYMER BY ATOM TRANSFER RADICAL POLYMERIZATION PROCESS

摘要

PROBLEM TO BE SOLVED: To provide a method for efficiently producing a vinyl-based polymer the structure of which is controlled.;SOLUTION: The method for polymerizing a vinyl-based monomer by an atom transfer radical polymerization process using a transition metal catalyst to produce the vinyl-based polymer is characterized in that the amount of an acid contained in the vinyl monomer is ≤10,000 mg-KOH/kg, that of an acid contained in a polymerization initiator is ≤100,000 mg-KOH/kg or that of an acid contained in a polymerization solution is ≤10,000 mg-KOH/kg.;COPYRIGHT: (C)2009,JPO&INPIT
