The concept of effective crosslinking density proposed by Scanlan is extended to heterogeneously crosslinking polymer. A kinetic-statistical model of effective crosslinking density of the gel is developed in free-radical heterogeneously crosslinking polymerization. The model is applied to the vinyl

SYNOPSIS
A general model of the gel/sol partition in the free-radical copolymerization of vinyl/divinyl monomers was developed, combining the statistical and kinetic modeling. It is emphasized that properties of the primary chains born at some conversion are effected by their partner primary chains. It was concluded that the present model had overcome some shortcomings in Flory's and Tobita's model and facilitated taking the influence of kinetics into account, and was shown to be rather general for the free-radical copolymerization of vinyl/divinyl monomers.

Based on our previous general model of the gel/sol partition, a model of the gel fraction of polymer is developed in the VC heterogeneously crosslinking suspension polymerization, where the kinetic factors such as two-phase polymerization mechanism, distinction of the gel and sol radicals, and the e
