Disclosed is an alicyclic diepoxy compound which gives a cured article suffering from no deterioration in properties even when used in hot and humid surroundings or used under such conditions as to give a strong acid, which is highly reactive upon curing, and which gives a cured article superior typically in thermal stability. Specifically, the alicyclic diepoxy compound includes a 3,4,3′,4′-diepoxybicyclohexyl compound represented by following Formula (1):
wherein R1 to R18 each represent a hydrogen atom, a halogen atom, a hydrocarbon group which may have an oxygen atom or a halogen atom, or a substituted or unsubstituted alkoxy group, in which the alicyclic diepoxy compound contains isomers of the 3,4,3′,4′-diepoxybicyclohexyl compound in a content of less than 20% based on the total of the 3,4,3′,4′-diepoxybicyclohexyl compound and the isomers thereof in terms of peak area ratio as determined by gas chromatography.
本发明揭示了一种脂环型双环氧化合物,即使在炎热
潮湿的环境或在产生强酸的情况下使用,也能产生没有性能恶化的固化制品,其在固化时具有高反应性,并且可以产生具有卓越热稳定性的固化制品。具体而言,所述脂环型双环氧化合物包括以下式(1)所表示的3,4,3′,4′-二环氧基双环己基化合物:其中R1至R18分别表示氢原子、卤素原子、可能具有氧原子或卤素原子的碳氢基团或取代或未取代的烷氧基团,在所述脂环型双环氧化合物中,3,4,3′,4′-二环氧基双环己基化合物的异构体含量低于20%,以气相色谱法测定的峰面积比为基础。
