SYNTHESIS AND EVALUATION OF BISBICYCLIC DIEPOXIDES
Abstract
synthesis of bis(2-(bicyclo(2.2.1)heptane-5, 6-epoxy)-methyl) oxide (diepoxide 262) was accomplished. The intermediate ether was obtained by the Williamson synthesis. The diepoxide can be cured with maleic anhydride and trimethylolethane to form a hard infusible resin. However, the resin obtained from this curing system is dark brown. A thin film of this same resin cured between salt plates was colorless. Curing temperature differences may account for the color differences noted between the two samples. Cure of 5,6-epoxy bicyclo(2.2.2)octane-2methyl-5',6'-epoxy bicyclo(2.2.2)octane-2carboxylate, synthesized during an earlier program, with maleic anhydride and trimethylolethane yielded a dark brown, brittle, thermoplastic material.
