The mechanical properties of polymers are strongly influenced by the molecular weight distribution of the polymer. Allegrezza (1972) in his study of the polymerization of substituted 3-lactones sought to modify some of the physical and mechanical properties of polyesters by broadening the Poisson distributed polymer produced in his preparations. His research provided the impetus for this continuing study. For a living polymerization, it is a simple task to develop a mathematical model of the reaction sequence which upon solution could yield information about conversion and molecular weight distribution.
