摘要 :

    Cobalt-mediated radical polymerization (CMRP) has shown a remarkable capability in controlling the polymerization of vinyl acetate (VAc) and vinyl monomers to produce the homo- and block copolymers with predictable molecular weight and narrow molecular weight distribution. We have devoted ourselves to developing CMRP, including synthesizing novel cobalt complexes, rationalizing the mechanism, and preparing innovative polymer materials. However, the removal of cobalt complexes from the polymeric products is always a barrier for industrial application. 

   Recently, we found a novel aluminum complex that can control the VAc polymerization via a mechanism similar to CMRP. Furthermore, an organic compound with only C, H, O, and N atoms, tralen, which was the ligand of the above aluminum complex, was recognized to be the control agent in the RDRP of vinyl acetate and methyl acrylate (MA). Inspired by these results, we reviewed the ligands in CMRP and identified another series of organic compounds, Schiff bases, which could mediate the RDRP of VAc and vinyl monomers. This new methodology using organic compounds as the mediator for the RDRP of VAc and MA, which shows limited toxicity and low cost, demonstrates a great potential to provide the route for the industrialization of PVAc-based homo- and block copolymers.
