Abstract
A series of new polyimides containing an s-triazine ring have been synthesized via Diels-Alder intermolecular polymerization of 2,6-bis(2-furanyl methyl imino)-4-n-propoxy-1,3,5-triazine with different bis(maleimide) compounds, rather than aromatization of corresponding Diels-Alder products. All the poly(imino-s-triazine imide)s were characterized by elemental analysis, FTIR spectral studies, number average molecular weight (Mn) by non-aqueous conductometric titration and thermogravimetry. Glass fibre reinforced composites were prepared via in-situ Diels-Alder intermolecular reaction between 2,6-bis(2-furanyl methyl imino)-4-n-propoxy-1,3,5-triazine and different bis(maleimide) compounds without evolution of by-products. The composites were characterized by chemical resistivity and mechanical properties.
