Samoilenko T. UV-cured simultaneous epoxy-acrylate interpenetrating polymer networks

The thesis is devoted to the synthesis of photocured simultaneous epoxy-acrylate interpenetrating polymer networks (IPNs) based on dimethacrylate and epoxides of different chemical nature under the irradiation of artificial and natural UV-radiation. Major results of the thesis were obtained by such research techniques as IR-spectroscopy, dynamic mechanical analysis, thermogravimetric analysis, the methods of refractometry, extraction, hydrostatic weighting, and light transmission. It was shown that the presence of epoxy component reduces the inhibition effect of atmospheric oxygen on the polymerization via free radical mechanism, and the presence of acrylate one - sensitizes the polymerization of aliphatic and cycloaliphatic-aliphatic epoxides via cationic mechanism. The reaction conditions (the absence or the presence of atmospheric oxygen), contrary to the type of the used source of UV-radiation, were revealed to influence the phase morphology and the properties of IPNs significantly. It was found that photocured simultaneous epoxy-acrylate IPNs are the promising materials for production of optically transparent protective coating for outdoor application.
