Beschreibung
Zusammenfassung:	Epoxy polymer precursors and epoxy polymers resulting therefrom are tolerant to bombardment by high-energy radiation. The epoxy polymer precursors comprise at least an epoxy resin free of aromatic units and at least a curing agent selected from the group consisting of aliphatic polyamines, cycloaliphatic polyamines, polyamides, aliphatic anhydrides, cycloaliphatic anhydrides, and mixtures thereof. In one embodiment of the invention the epoxy resin comprises at least a cycloparaffinic group, and the curing agent comprises a polyamine derived from cyclohexane. Such epoxy polymer compositions are used to form reflectors elements between adjacent scintillator elements in high-energy radiation detector array.
