Synthesis of Fully Biobased Semi-aromatic Furan Polyamides with High Performance through Facile Green Synthesis Process

Abstract Biobased polymers hold the promise of addressing climate change and biodiversity loss due to deriving from renewable carbon. Dimethyl furan-2,5-dicarboxylate as a biobased monomer is potential alternative of terephthalic acid and has been widely used to produce biobased polyesters or polyamides. In this study, excellent performance of poly(decamethylene furanamide) (PA10F) was synthesized via bulk polymerization with 1,5,7-triazabicyclo[4.4.0]dec-5-ene (TBD) as catalyst. PA10F produced at 200 °C as well as 0.05 MPa, weight-average molecular weight, glass transition temperature (Tg) and initial decomposition temperature (Td-5%) were up to 62500 g/mol, 103 °C and 401 °C, respectively. Furthermore, the mechanical properties were also outstanding with the maximum tensile strength of about 54.46 MPa, elongation at break of about 138.60 %, and tensile modulus of about 1454 MPa. According to the result of X-ray diffraction analysis, the PA10F was amorphous.
