Synthesis and Characterization of Partial Biobased Furan Polyamides

Abstract

We have used two synthetic methods, direct polycondensation and interfacial polymerization, to prepare partially biobased furan polyamides from the biobased monomer, 2,5-furan dicarboxylic acid, a product of carbohydrates, and p-phenylenediamine. Polyamides synthesized from interfacial polymerization provided consistent molecular weight values averaging 24,000 g/mol. These materials show limited solubility in some organic solvents like acetone and chloroform; however, they are highly soluble in sulfuric acid and polar aprotic solvents anhydrous dimethylformamide, anhydrous 1-methyl-2-pyrrolidinone, and dimethyl sulfoxide. Thermal analysis measurements of the partially biobased polyamides have shown an average thermal stability of 400 deg C, compared to that of manufactured petroleum-based Kevlar (T[sub d], 427 deg- 482 deg C), and T(sub g) values have been observed to be greater than the degradation of the polymer materials.
