<p>Disclosed are epoxy resin compositions comprising at least one polyglycidyl derivative of an aminophenol having the structure and at least one biphenyl anhydride having the structure wherein m is 1 or 2; wherein A is selected from the group consisting of and , wherein each R.degree. is individually a monovalent radical selected from the group consisting of hydrogen, halogen, hydroxy, alkyl radical having from 1 to 5 carbon atoms, alkoxy radical having from 1 to 5 carbon atoms and , wherein R1 is an alkyl radical having from 1 to 5 carbon atoms; and wherein each R2 is individually a monovalent radical selected from the group consisting of hydrogen, halogen, alkyl radical having from 1 to 5 carbon atoms, -N02, -COOH -S03H, and -NH2. The compositions are useful in such applications as molding resins, laminates, adhesives, coatings and the like. The disclosed epoxy resin-anhydride systens can be cured at ambient temperatures to afford products having useful properties at high temperature.</p> |
