photopolymerization

The activity of the photoinitiator system, based on triethanolamine (TEOA) and methylene blue (MB), on the photopolymerization of hydroxyethyl acrylate (HEA) monomer under very soft irradiation conditions, was evaluated. A remarkable difference in the polymerization kinetics of a set of PHEA experiments was underlined according to TEOA/MB concentrations, as well as the solutions pH.

The photosensitivity of 2-hydroxyethyl methacrylate- polyvinyl pirrolidone- iron salt (ІІІ) compositions with different content of polyvinyl pirrolidone and its influence on the structure and properties of polymerization products is investigated. The results of research make it possible to correct photosensitivity of mentioned compositions and properties of the polymers on their basis depending on changes in the polyvinyl pirrolidone content.
