Epoxyesteracrylate materials hardened by radiation-chemical and photochemical methods in air medium

Considered is the possibility of using compositions on the base of modifying products of unsaturated epoxy oligomers with dicarboxylic acids for getting coatings of radiation-chemical hardening on wood. Irradiation of coatings by electrons with energy of 1-300 MeV was carried out in open air. Current intensity in electron beam equaled 20 to 0.05 mA. Epoxysuccinacrylate was shown to be the most active oligomer in a process of radiation copolymerization. Acrylic acid, butylacrylate, vinylacetate are the most active monomers. Dozes, necessary for coating adhesiveness removal under the irradiation, are within 5.5-25.5 Mrad. Some physicochemical characteristics of coatings hardened by radiation chemical method on wood are given
