A novel composition is disclosed comprising an alicyclic epoxy compound formed by an epoxidation reaction of a polymerized cyclo olefin compound having double bonds with an epoxidating agent. A cured epoxy resin according to the present invention has excellent heat resistance, outdoor durability, and water resistance, attributable to the absence of ether units derived from the ring-opening of epoxy groups and hydroxyl groups derived from an initiating agent.

Composition comprising an epoxy compound

Disclosed are a composition comprising polyether compounds, obtained by addition copolymerization of a mixture of 4-vinylcyclohexene-1-oxide and a compound having at least two epoxy groups with a compound having at least one active hydrogen atom, and a composition comprising epoxy compounds obtained by epoxidation of the composition of the polyether compounds. The invention also relates to processes for production thereof. The disclosed composition comprising epoxy compounds has a higher softening temperature compared that produced by polymerization of only 4-vinylcyclohexene-1-oxide with a compound having at least one active hydrogen atom.
