Photopolymerization of Multifunctional Monomers. Time Dependence of Polymerization Kinetic Constants According to Various Models of Termination Process

The time behavior of kinetic constants during dark reaction after cutting off the irradiation of a multimethacrylate-based polymerizing system was studied. The initiation was stopped at various
degrees of double bond conversion. The kinetic constants were determined from three termination
models: monomolecular, bimolecular and mixed. Discussion concerns the dependence of bimolecular termination rate constant, monomolecular termination rate constant and propagation
rate constant on postpolymerization time.
