On the Whiteway–Smith–Masson and Flory–Stockmayer Theories of Polymerization

A computer simulation of random polymerization reveals that the Flory–Stockmayer expression describes a model where functional groups are of equal reactivity and all chain and ring configurations are allowed. The Whiteway–Smith–Masson expression describes a model in which rings are formally forbidden by a technique that requires departure from the principle of equal reactivity. The apparent conflict between the two theories thus is resolved, and each appears to have application in describing various real systems.
