Abstract
PURPOSE: To obtain a thermosetting composition which is easy in mixing operation and good in storage stability and provides moldings, coated films, etc., having excellent heat resistance, mechanical strength, electric properties, etc., by adding a specific tetrabasic acid anhydride to an epoxy resin.
CONSTITUTION: Into a molding frame is poured a composition obtained by mixing, under heat, 3-methy1-5-anhydrosucciny1-3-cyclohexene-1,2-dicarboxylic acid anhydride of formula I with an epoxy resin having at least one epoxy group in the molecule and mixing; after cooling, the resulting mixture is heat-cured with a curing agent such as benzylamine. In an alternative method, said tetrabasic acid anhydride and an epoxy resin are dissolved in a solvent such as acetone, and mixed with a curing agent. The resulting solution is used as an adhesive for laminating materials. In this way, moldings having a high heat distortion temperature and laminated sheets having excellent electric properties are obtd. The composition can also be used as a powder paint.
