摘要：

The synthesis of well-defined poly(vinyl acetate) in ''living'' radical polymerization is reported. Straight lines in semilogarithmic plots up to >90% conversion indicate internal first order in monomer and a constant concentration of growing species. Molecular weights increase linearly with conversion. The initiating system might,involve persistent radical formed by the ternary complexes of organoaluminum compounds with Lewis bases and stable radicals. This article focuses on the Al(iBu)(3):BPy:TEMPO system. The effect of the composition of the initiating system and its aging is described.
