Abstract

In the present work, a library of distortional diamines based on 1,3-phenylenebis((4-(4-aminophenoxy)phenyl)methanone) (AEK-134) are assessed for their thermomechanical properties with N,N′-tetraglycidyl diaminodiphenylmethane (TGDDM). Effects of isomerism and hydrogen bonding on Young's modulus, yield strength, ultimate compression and toughness are dicussed. Diamine basicity (pKb) is correlated to both the activation energies required for oxirane-amine ring opening as a function of conversion and the kinetics of oxirane-amine ring opening.
