Kytsya A. Monomolecular chain termination in the postpolymerization kinetic of bifunctional monomers

Kinetics of postpolymerization (after the UV-illumination stopping) for five dimethacrylates has been studied. Kinetic model of process, which is based on the conception of a microheterogeneity of polymerizing system with the assumption about a wide spectrum of characteristic times of monomolecular chain termination is proposed. It was determined, that constants rate of chain termination have an activation nature; constants rate of chain termination is a function of dimethacrylate nature with the scaling dependence upon concentration of monomer in the bulk. The same nature of monomolecular chain termination for linear and 3D polymerizations is indicated. The stretched exponential law for relaxation function of monomolecular chain termination has been derived. The new method of adhesive conjunction of non-transparent substrates, based on the post-effect was proposed.
