A newly developed kinetic model for network structure development during emulsion crosslinking copolymerization of vinyl and divinyl monomer is used to investigate the kinetics of emulsion crosslinking copolymerization of methyl methacrylate and ethylene glycol dimethacrylate. The agreement of predicted with measured development of crosslinking density and that of monomer concentration in the polymer particles is found to be satisfactory. It is shown that the crosslinking density is fairly high even from very early stages of polymerization and that the produced polymeric networks tend to be highly heterogeneous. The kinetics of crosslinking and resulting network structure are essentially different from those for polymerizations in homogeneous media such as bulk and solution polymerization.
