Controlled/living radical polymerization has been known as useful technique for the preparation of a well-defined polymer structure by controlling molecular weight, molecular weight distribution, and tailored architecture. Based on the radical capping mechanism and agents, controlled/living radical polymerizations are generally classified. In this study, we have demonstrated that 4-toluic acid dithiobenzoate is effective RAFT agent in the solution polymerization of acrylonitrile. A linear increase in molecular weight with respect to conversion is observed, which indicates the polymerization is controlled. Increasing molar ratio of RAFT agent to initiator, the lower molecular weight and molecular weight distribution were obtained. |
