Abstract Novel copolyesters were successfully synthesized from terephthalic acid (TPA), 2,5-furandicarboxylic acid
(FDCA) and ethylene glycol, 1,3-propanediol, 1,4-butanediol, 1,6-hexanediol and 1,8-octanediol via direct
esterifi cation method by using tetrabutyl titanate (TBT) as catalyst. The copolyesters were characterized
by nuclear magnetic resonance spectroscopy (1
H-NMR), gel permeation chromatography (GPC), X-ray
diffraction (XRD), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA) and tensile
tests. The results of GPC showed that all of the copolyesters had high molecular weight, with an average
molecular weight (Mw) more than 1×104
g/mol. The results of 1
H-NMR showed that the copolyesters were
random copolymers which compositions were well… More >
