Abstract

Curing of Bisphenol A diglycidyl ether with methylendic anhydride under the action of imidazole-type catalysts was studied by differential scanning calorimetry and IR spectroscopy. The curing system with the optimum catalyst content was chosen. Heat-resistant polymers and composites with high values of the glass transition point, elastic modulus, and tensile, compression, and bending strength were prepared from epoxy resins of various functionalities.
