Abstract

An ammo-terminated oligoimide was prepared by the Michael addition reaction of ethylene bismaleimide (EBM) and 4,4′-diamino diphenyl methane (DDM) at an EBM:DDM molar ratio of 1:2. The poly(amido-imide)s (PAI)s were prepared by condensation of this EBM:DDM oligoimide with various aliphatic bisesters. The resultant PAIs were characterized by elejnental analysis, IR spectral studies, and the number average molecular weight ( $\bar{M}$ n) estimated by non-aqueous conductometric titration and thermogravimetry. The curing-reaction of an epoxy resin (a diglycidyl ether of bisphenol-A (DGEBA)) with PAI was monitored by Differential Scanning Calorimetry (D.S.C.). Glass and carbon fibre reinforced laminates of PAI-epoxy resin were also prepared and characterized.
