| Abstract: | The electron beam curred(EBC) coating composed of epoxyacrylates resin as oligomer have been used in vast area. The microstructure of the coating is closely correlated with moleculers structure the components and radiation dose during curing. The S-parameter of positron annhilation doppler broadening was measurred as a function of positron energy to study electron irradiation induced polymerization and crosslinking. The correlations of S-parameter with content, moleculers structure of reactive diluent, and irradiation dose were observed. |
