Bis(epoxytetrahydrodicyclopentadienyl) ether (Ⅱ)

bis(epoxytetrahydrodicyclopen-tadienyl) ethylene glycol ether (Ⅲ) and bis(epoxytetrahydrodicyclopentadienyl)-tetramethylene glycol ether (Ⅳ) were synthesized. These diepoxides can be cured with acid anhydride mixed with glycerol

the order of cure rate is: (Ⅱ) > (Ⅲ) > (Ⅳ). The temperature-deformation curves of casting from these diepoxides were determined

the thermo-mechanical property of casting from (Ⅲ) was analogous to (Ⅳ)

but both were inferior to (Ⅱ).The thermo-mechanical property of casting from (Ⅱ) was ap-proximate to dicyclopentadiene dioxide

but it was liquid and cured with faster rate.
