Studies on poly(ester-urea-imide)s containing epoxy segment
Novel flame retardant poly(ester-urea-imide)s were prepared by diels?Alder (DA) polymerization reaction of various bisfuran derivatives (3a?e) containing amide linkages with brominated epoxy resin based bismaleimide (4). The so-called DA reaction was carried out by refluxing the mixture of both 3a?e and 4 monomers in THF solvent. The resultant DA adduct was formed which was treated with acetic anhydride at 135?C. The final products were in aromatized form and designated as poly(ester-urea-imide)s (PEUIs, 6a?e). These polymers were characterized by elemental analysis, number average molecular weight and thermogravimetric analysis. The glass and carbon fiber reinforced composites of such PEUIs were fabricated by ?in situ? polymerization process.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Reference of 17057-04-4. In my other articles, you can also check out more blogs about 17057-04-4
