Cycloaliphatic polyepoxy compounds and preparation thereof
Is disclosed a cycloaliphatic polyepoxy compound represented by following Formula (1):wherein Y represents a linkage group or a single bond; and HAs each represent hydrogen atom at the junction between cyclohexane ring and oxirane ring, and the cyclohexane rings may each further have one or more substituents in addition to the groups shown in the formula. The cycloaliphatic polyepoxy compound contains stereoisomers in such proportions as to have a ratio A/B of 1.8 or more, wherein “A” and “B” are integrated intensities of signals of protons at the junction between cyclohexane ring and oxirane ring as determined by 1H-NMR spectroscopy of the compound, in which “A” represents the integrated intensity of a signal observed at a lower magnetic field, and “B” represents the integrated intensity of a signal observed at a higher magnetic field.
