Abstract

It is still impossible to estimate the distribution of the molecular-weight (chain-length) between two crosslinks of a crosslinked polymer, because of its insolubility and infusibility. The distribution p (x) of chain-length between crosslinks x will be estimated by chemorheological means. If the scission rate of chain is proportional to x, the rate of stress relaxation due to the main chain scission is related to p(x) through Laplace transformation. p (x) thus obtained is likely to indicate the real distribution, because the same reault can be obtained for a given crosslinked polymer from different chemical stress relaxation curves at different high temperatures.
