摘要

Abstract

In order to explore new substitutes for 2

5-furandicarboxylic acid (FDCA) or poly(ethylene 2

5-furandicarboxylate) (PEF) and try to develop more ideal bio-based polyesters

several thiophene-aromatic polyesters (PETH

PPTH

PBTH

and PHTH) were synthesized from dimethyl thiophene-2

5-dicarboxylate (DMTD) and different diols

including ethylene glycol

3-propanediol

4-butanediol

and 1

6-hexanediol. The chemical structures of obtained polyesters were confirmed by nuclear magnetic resonance spectroscopy (

H-NMR and

C-NMR). Determined by GPC measurement

their average molecular weight (

) varied from 5.22 × 10

g/mol to 7.94 × 10

g/mol with the molar-mass dispersity of 1.50−2.00. Based on the DSC and TGA results

the synthesized polyesters PETH

PPTH

and PBTH displayed comparable or even better thermal properties when compared with their FDCA-based analogues. From PETH to PHTH

their

varied from 64.6 °C to −1 °C while

ranged from 409 °C to 380 °C in nitrogen atmosphere. PETH showed elongation at break as high as 378%

tensile strength of 67 MPa

and tensile modulus of 1800 MPa. Meanwhile

the CO

and O

barrier of PETH was 12.0 and 6.6 folds higher than those of PET

respectively

and similar to those of PEF. Considering the overall properties

the synthesized thiophene-aromatic polyesters

especially PETH

showed great potential to be used as an excellent bio-based packaging material in the future.
