Abstract

Gamma radiation curing of an epoxy monomer, in the presence of an iodonium salt, as initiator, is studied. Systems have beenpolymerized at the same irradiation dose and dose rate and at different processing temperatures. The experimental results show that allthe irradiated materials exhibit a latent reactivity, undergoing toward an increase of crosslinking density if they are thermally cured afterirradiation. The results indicate that the processing temperature affects both the crosslinking density after irradiation and the sensibilityto the post-irradiation thermal treatment.
