Abstract

PURPOSE: To provide the titled compsn. which has excellent workability and does not precipitate crystals of a free carboxylic acid during moisture absorption, by a method wherein a polycarboxylic acid anhydride consisting mainly of specified methylhexahydrophthalic anhydrides as a hardener is blended with an epoxy resin.
CONSTITUTION: In the production of methylhexahydrophthalic anhydride which is a hardener for epoxy resins, by using isoprene and maleic anhydride as the starting materials, the hydrogenation stage is carried out at a lower temperature to reduce the amount of 4-methyl-Δ3 tetrahydrophthalic anhydride contained in methyltetrahydrophthalic anhydride to 0.1wt% or below and also to give a ratio of 4-methylhydrophthalic anhydride to 3-methylhexahydrophthalic anhydride in methylhexahydrophthalic anhydride of 75/25W25/75. Then the resulting methylhexahydrophthalic anhydride as a hardener is blended with an epoxy resin to obtain the titled resin compsn.
