Kinetics of multifunctional (meth)acrylates photopolymerization in the presence of aromatic imidazole

The photolysis of phenanthroline-containing imidazole in DMSO solution and the initiating ability of the compound in photopolymerization of multifunctional (meth)acrylates under LED irradiation (λ = 395 nm) under aerobic conditions were investigated for the first time. The relationship of kinetic parameters of photopolymerization with light intensity, chemical structure, and viscosity of multifunctional monomers was established.
