Abstract
A novel compound 5-(2,4-dioxotetrahydro-3-furanylmethyl)norbornane-2,3-dicarboxylic acid anhydride has been provided. The compound is prepared by hydrogenating 5-(2,4-dioxotetrahydro-3-furanylmethyl)-5-norbornene-2,3-di-carboxylic acid anhydride. The compound may be used as a hardening agent for epoxy resins, a raw material of producing polyimides, polyamides and polyesters, and a raw material for a plasticizer for vinyl chloride polymers.
