Abstract In this investigation, a synthetic biopolymer prepared from bithiophene monomer, isosorbide and ethylene glycol, was synthesized through melt polycondensation. The result showed the polyesters to possess promising thermal and mechanical properties. The bithiophene monomer, [2,2'-bithiophene]-5,5'-dicarboxylicacid acid, was synthesized from a palladium-catalyzed, phosphine ligand-free direct coupling protocol, using polyethylene glycol palladium (Pd/PEG) as catalyst. The procedure was found effective at polymerizing the bithiophene monomer with isosorbide and glycol. The bithiophene polyester displayed several intriguing properties among good thermal resistance, crystallinity and high tensile modulus. Additionally, the bithiophene monomer coupled to isosorbide enhanced the polyester with a comparatively high glass transition temperature. Films cast out these polyesters display excellent oxygen and water barrier properties, and were interestingly superior to those of poly(ethylene terephthalate). Moreover, the novel polyester also has good soil degradability properties.
