Polyamide composed of furan dimer, which is prepared from biomass-derived organic molecule 2-furfural, is synthesized. The reaction of 2,2-furan dimer 5,5-dicarbonyl chloride with several 1,-diamines was carried out with a solution or interfacial polycondensation leading to the corresponding polyamide. Measurement of the melting point was performed resulting to exhibit a higher temperature compared with the related polyamide bearing a single furan ring composed of furan-2,5-dicarboxylic acid (FDCA). Thermal analyses (TG-DTA) also indicated higher temperatures of decomposition than those of FDCA-derived polyamide. (c) 2018 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym.
