Novel polyimides containing s-triazine nucleus were prepared via Diels-Alder (DA) intermolecular polymerization of 2,4-bis(2-furanyl methyl imino)-4-methoxy-1,3,5-triazine (1) with different bis(maleimido) compounds (2a-h). The DA reaction was carried out in tetrahydrofuran as solvent, as well as in bulk followed by dehydration on aromatization of poly(tetrahydrophthalimido)-intermediates (3a-h) in the presence of acetic anhydride. All the poly(imino s-triazine imide)s (4a-h) were characterized by elemental analysis, IR spectral studies, and thermogravimetry. 1 and 2a-h were polymerized (at 150±10°C) by in-situ Diels-Alder intermolecular reaction into poly(imino s-triazine imide)s-glass fibre reinforced composites (i.e., laminates) without evolution of bi-products. The prepared composites were characterized by chemical resistivity and mechanical properties. |
