SYNTHESIS METHOD FOR POLYMERS BY CONTROLLED RADICAL POLYMERISATION WITH XANTHATES

摘要

The invention concerns a method for preparing polymers, characterised in that it consists in contacting: at least an ethylenically unsaturated polymer, at least a source of free radicals, and at least a compound of general formula (IA) wherein R<2> represents a group of formula (I); R<3> being advantageously an electron-attracting group.
