Abstract

A computer simulation model is used to study the kinetics of gelation of a low concentration of bifunctional ( C2) and tetrafunctional ( C4) monomers on a simple cubic lattice. The mobilities of the monomers and the microgel particles are considered. Monomers react with their neighbors with a certain probability after hopping with a fixed number of steps. Growth of the concentration of saturated bonds, weight average degree polymerization, and the volume fraction of the gel are studied as a function of reaction time. We find that the critical gel time (i.e. the gel point) depends nonlinearly on the mobility steps of hopping.
