• Studies on a New Rapid and Simple Determination Method of Chain-Length Distribution of a Crosslinked Polymer by Chemorheology

抄録

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.<BR>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 result can be obtained for a given crosslinked polymer from different chemical stress relaxation curves at different high temperatures.
