Radiation hardening of oligomer-epoxy composition

Radiation chemical hardening of compositions in a thin layer is considered along with the effect of component nature on molecular mobility of formed coatings. Investigations on compositions containing epoxy oligomers with different nature, acryl monomers and unsaturated oligomers were carried out. Hardening of compositions was performed under the action of accelerated electrons. To study the molecular mobility of polymers, stable radicals were used as a probe. Coatings on the base of compositions containing aromatic epoxy oligomer and aliphatic oligoesteracrylate are found to be less structurized compositions in each group
