摘要：

Fully biobased poly(butylene sebacate-co-butylene furandicarboxylate) (PBSFs) copolyesters were synthesized using a two-step melt polycondensation method from 2,5-furandicarboxylic acid (FDCA), sebacic acid(SA), and 1,4-butanediol (BDO). The composition, molecular weight, crystal structure, and thermal properties of PBSFs were investigated by H-1 NMR, GPC, WAXD, DSC and TGA, respectively. Tensile properties were also evaluated. The number average molecular weight (M-n) ranges from 35600 to 46200 g/mol. PBSFs are all random copolyesters and exhibit excellent thermal stability. The glass transition temperature (T-g) and melting point temperature (T-m) of PBSFs gradually decreased with the increasing of butylene sebacate (BS) unit content (phi(BS)). Compared with poly(butylene furandicarboxylate) (PBF), PBSFs exhibit lower T-g and crystallinity. Thus, the ductility of PBF is substantially improved (the elongation at break (epsilon(b)) of PBSFs ranges from 100 to 780%). (C) 2017 Published by Elsevier Ltd.
