N,N'‐Diglycidylimides and their polymers

At first new epoxy derivatives, namely glycidylimide compounds, have been prepared using benzyltrimethylammonium chloride as catalyst and epichlorohydrin in excess. Their chemical and physical properties were studied. Spectral data confirmed these new structures. Afterwards new epoxy resins have been synthesized by the reaction of diimides and their glycidyl derivatives in N,N‐dimethylformamide. The physical characteristics of the obtained polymers and also their solubilities are reported. Their IR, 1H‐ and 13C‐NMR spectra allowed to confirm the polymer structure. Thermal analysis of these compounds showed their good thermal properties.
