Abstract

The 'living'/controlled radical polymerization of PS-b-PIVDG was successfully achieved using 2,2'-azobis(isobutyronitrile) as the initiator and PS 'living' chain as the macro-reversible addition-fragmentation chain transfer(RAFT) agent at 60℃ in tetrahydrofuran.The number-average molecular weight of the obtained polymers increased in direct proportion to the monomer conversion,and the molecular weight distribution was narrow(polydispersity index 1.2).The chain structures of the obtained PS-b-PIVDG were confirmed with the 1H-NMR analysis.
