Zusammenfassung:	PURPOSE:To obtain a new compound useful as a subsidiary raw material for modifying agents or resin compositions of synthetic resins. CONSTITUTION:An esterified butanetetracarboxylic acid anhydride of the formula (R and R are 4-30C alkyl, alkenyl or aralkyl). The compound is obtained by dehydrating an ester group-containing compound obtained from 1,2,3,4- butanetetracarboxylic acid and/or its anhydride and an alcohol containing 4-30C alkyl, alkenyl or aralkyl at 160-300 deg.C. The compound of the formula can provide flexibility, water resistance and hydrophobic properties to an epoxy resin and an polyester resin. The alcohol is exemplified by stearyl alcohol, lauryl alcohol, etc., and is used in an amount of 1-4 times by weight based on butanetetracarboxylic acid.
