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-butoxy-1,3,5-triazine with different bis(maleimide) compounds first and then aromatization of the corresponding Diels-Alder products. All the poly(imino-s-triazine imide)s were characterized by elemental analysis, FT-IR spectral studies, number-average molecular weight (M n) by non-aqueous conductometric titration, and thermogravimetry. Glass fibre-reinforced composites were prepared via an in situ Diels-Alder intermolecular reaction between 2,6-bis(2-furanyl methyl-imino)-4-n-butoxy-1,3,5-triazine and different bis(maleimide) compounds, without evolution of by-products. The prepared composites were characterized by chemical resistivity and mechanical properties.
