Calculation of network parameters of crosslinked markovian polymer chains

Abstract

Linear copolymer chains form in a chain‐addition reaction which includes initiation, homopropagation, crosspropagation, and termination by transfer, disproportionation, and combination. Chain growth obeys the Markov property. Multiple types of monomeric units are involved; some types have reactive sites, others do not. These chains are then crosslinked by a small monomer crosslinker which may have a polydispersed distribution of functionality and mass. The resulting network consists of soluble, pendant, and elastically effective fractions. Using classical Markov chain analysis techniques, various statistical properties of the polymer chains are computed. The gel point, weight fractions and other network properties can then be calculated. The effects of unequal rates of chain homopropagation and crosspropagation can be observed.
