Polyacrylonitrile-block-poly(methyl acrylate)(P(AN-b-MA)) was synthesized by reversible addition-fragmentation chain transfer (RAFT) polymerization employing macro-RAFT agent (PAN-RAFT) as the chain transfer agent and azobis(isobutyronitrile) (AIBN) as the initiator. A linear relationship between ln([M]0/[M]t) and reaction time was observed. The molecular structure of P(AN-b-MA) was characterized by 1H-NMR, element analysis, FTIR and SEC. The molecular weight distribution (MWD) was less than 1.40, the Mn could be controled from 0.733 to 4.834×104, and the molar content of MA in P(AN-b-MA) were from 15.6 to 75.0 percentage, respectively.
