Abstract
In consideration of the modern idea of reptation, it is proposed that the rate of termination is proportional to n−1/2(n=chain length) when n is less than a critical chain length nc, but the rate is proportional to n−2 when n>nc. The molecular weight in terms of the gel effect is calculated by using such a rate. This molecular weight fits sufficiently to the experimental molecular weight obtained previously in a radical polymerization of methyl methacrylate. Further, the rate constant of termination between small polymer radicals is discussed by the free volume theory.
