Study on electron beam curing resins

Using electron beams to initiate polymerization reactions is an area on which much interest has been focused. The curing of vinyl monomers such as acrylates and maleimides by means of high energy electron beam irradiation normally proceeds via a free-radical mechanism while e-beam-induced polymerization of epoxy resins proceeds via a cationic mechanism in the presence of an appropriate photoinitiator. This work is used to investigate the synthesis of new maleimides, aromatic imide monomers, active PMR polyamide acid and silaceous acrylates containing vinyl groups. The cure activity of these vinyl monomers was conducted, so as the epoxy resins. The results suggest that the potential curability exists in the active groups and the structure of the chain.
