Abstract
We present an efficient method for synthesis of block copolymer by radical addition cross-coupling reaction between two different polymeric radicals and different double bonds. Two different monobromo polymers (P1-Br and P2-Br) were reacted with Cu(0)/N,N,N′,N″,N″-pentamethyldiethylenetriamine in the presence of ethyl dithiobenzoate or 1,1-diphenylethylene (X) and the block copolymer (P1-X-P2) can be obtained with high efficiency, which cannot be prepared by normal atom transfer radical coupling of mixture of P1-Br and P2-Br. © 2013 Wiley Periodicals, Inc.
