| Abstract: | Poly(amido-imide)s (PAI) were prepared by the intermolecular Diels-Alder (DA) reaction of 1,1-(sulfonyldi-4,1-phenylene) bis[(2-furanyl methylamino) acetamide] (SPBFA) with various bis(maleimide)s. The DA reaction was carried out in tetrahydrofuran as a solvent, as well as in bulk, followed by aromatization of sodium acetate intermediates in the presence of acetic anhydride. All the polymers were characterized by elemental analysis, infrared (IR) spectral studies, and thermogravimetry. The PAI exhibit moderate thermal stability. The SPBFA and bis(maleimide)s were polymerized (at 145±10°C) by in situ DA intermolecular reaction into moderately thermally stable PAI-glass fiber composite laminates and were characterized by their chemical resistance and mechanical properties. |
