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 1×10
4
g/mol. The results of
1
H-NMR showed that the copolyesters were
random copolymers which compositions were well controlled by the feed ratio of the diacid monomers,
and the degrees of randomness (B) values were near to 1.0 and 1.40. The results of DSC showed that all of
the copolyesters had one glass transition temperature (T
g
) and the T
g
s were between those of corresponding
homopolyesters. The results of TGA showed that the copolyesters were thermally stable up to 370°C and had
similar thermal stabilities to corresponding homopolyesters. The results of tensile tests showed that some of
the PETF and PTTF copolyesters had better tensile strength and tensile modules, and PBTF, PHTF and POTF
copolyesters had higher elongation at break.
