Abstract
Block copolymers, poly(LLA-b-St)s and triblock copolymes, poly(LLA-b-St-b-MMA)s have been synthesized by the combination of the atom transfer radical polymerization (ATRP) with ring-opening polymerization (ROP) using bifunctional initiator β-hydroxylethyl α-bromoisobutyrate (HEBIB) without intermediate function transformation. The molecular weight (MW) and the molecular weight distribution (MWD) can be controlled. The structures of the copolymers were confirmed by 1H NMR spectroscopy and GPC.
