The present invention provides a polymer precursor composition that resists damage caused by high energy radiation and a polymer obtained therefrom. (A) an epoxy resin having a plurality of oxirane groups and containing no aromatic unit; and (b) an aliphatic polyamine, an alicyclic polyamine, a polyamide, an aliphatic anhydride, an alicyclic anhydride, and And a curing agent selected from the group consisting of these mixtures. (The epoxy resin is selected from the group consisting of butadiene dioxide, dimethylpentane dioxide, diglycidyl ether, 1,4-butanediol diglycidyl ether, diethylene glycol diglycidyl ether, dipentene dioxide, polyol diglycidyl ether, and mixtures thereof. Such compositions are used to form reflector elements between adjacent scintillator elements in a high energy radiation detector array. [Selection diagram] Fig. 1 |
