Abstract

Two bisphenol-A type epoxy resins were irradiated by electron beam and studied afterwards by positron lifetime spectroscopy. An interesting result is that despite the considerable amount of free-radicals no inhibition of positronium formation was observed in the two epoxies. Nevertheless several serious differences were detected between the studied polymers. The results suggest that the radiation-resistant properties of epoxies depend strongly on the amount of the curing agent.
