Abstract:

Synthesis of well-defined polyvinyl 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 radicals formed by the ternary complexes of organoaluminum compounds with Lewis bases and stable radicals. This article focuses on AliBu3DPyTEMPO system. The effect of the composition of the initiating system and its aging is described.
