Novel epoxy resin and production thereof
Abstract
Abstract NEW MATERIAL:A novel epoxy resin expressed by formula I. USE:An epoxy resin composition with superior heat resistance, impact resistance, heat-shock resistance, water resistance and mechanical properties such as strength. PREPARATION:One mol diamine expressed by formula II is subjected to addition reaction with 4-40mol epihalohydrin (epichlorohydrin, etc.), and 4-8mol alkali are added thereto and stirred at 20-80 deg.C to carry out dehydrohalogenation reaction. After the reaction has finished, salts, catalysts, etc., in the reaction mixture are filtered and the solvent is distilled away at 50-170 deg.C under reduced pressure.
