Notes:
Epoxy compounds such as allyl glycidyl ether, phenyl glycidyl ether, and Epicote 812, which are not polymerizable by irradiation, were irradiated by γ-rays to a total dose of 1 × 107-2 × 108r, and decomposition of epoxy radicals was examined. The result showed that epoxy radicals are more or less radiation-resistant and for the greater part remain unchanged. Methacryl glycidyl ester, which is polymerizable by irradiation, was radiation-grafted to polyethylene and to polytetrafluoroethylene by simultaneous irradiation with γ-rays, and the degree of grafting was checked. Two sheets of radiation-graft polyethylene or polytetrafluoroethylene were bonded with epoxy resin adhesives containing polyamide hardener, and bond strength was examined. This showed that the bond strength of grafted polymer is larger than that of the nongrafted one.
