Abstract: DISCLOSED ARE UNCURED POLYEPOXIDE RESIN COMPOSITIONS COMPRISING A POLYEPOXIDE CONTAINING OXIRANE GROUPS TOGETHER WITH A METHYL-NORBORNANE-2,3-DICARBOXYLIC ANHYDRIDE AS CURING AGENT, PREFERABLY IN THE PRESENCE OF AN ACCELERATING AGENT, SUCH AS A TERTIARY AMINE OR AN ORGANO METALLIC COMPOUND, AND CURED POLYEPOXIDE RESINS PRODUCED THEREFROM. ALSO DISCLOSED IS PRODUCTION OF NOVEL LIQUID ANHYDRIDE COMPOSITIONS COMPRISING A MIXTURE OF 1AND 5-METHYL-NORBORNANE-2,3-DICARBOXYLIC ANHYDRIDES PRESENT IN A WEIGHT RATIO NO GREATER THAN ABOUT 3:1, AT LEAST ABOUT 40 WEIGHT PERCENT OF SAID 5-METHYL ISOMERS OF SAID MIXTURE BEING OF EXO-CONFIGURATION, BY HEATING AN ANHYDRIDE MIXTURE COMPRISING ENDO-1- AND 5-MEHTYL-5NORBORNENE 2,3-DICARBOXYLIC ANHYDRIDES AT AN ELEVATED TEMPERATURE IN THE PRESENCE OF HYDROGEN. THE POLYEPOXIDE COMPOSITIONS DISCLOSED ARE SUBSTANTIALLY LESS VOLATILE DURING CURING AT ELEVATED TEMPERATURES, AND CURED RESINS PRODUCED THEREFROM EXHIBIT SUPERIOR MECHANICAL PROPERTIES AND ARE OF LIGHTER COLOR AS COMPARED WITH CURED RESINS PRODUCED FROM POLYEPOXIDE COMPOSITIONS DERIVED FROM KNOWN CYCLOALIPHATIC ANHYDRIDE CURATIVES. THE LIQUID NOVEL ANHYDRIDE COMPOSITIONS DISCLOSED ARE STORAGE STABLE FOR EXTENDED PERIODS OF TIME WITHOUT DEPOSITION OF SOLIDS AND CHANGE OF COLOR, AND ARE STABLE TO CHANGES IN TEMPERATURES BELOW DISTILLATION TEMPERATURES.
