Summary

A fragment approach, consisting of a selection of different fragments from which the network may be built-up, together with a kinetic scheme giving the evolution of such fragments during polymerization and a recursive approach for derivation of statistical averages, is used in the analysis of the build-up of polymer networks by initiated polyreactions. Gelation conditions are predicted for two simple cases: the living polymerization of a (tetrafunctional) monomer with two polymerizable groups and the polyetherification released by polyamine-polyepoxide addition. When the size of the fragments is increased, the solution converges to the exact solution given by the kinetic theory.
