ABSTRACT:
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.
