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.

Abstract The phase morphology, thermal behavior and mechanical properties of two series of polymer blends based on ethylene/propylene/diene rubber (EPDM) and amorphous homologues of poly(ethylene terephthalate), i.e. glycol modified poly(ethylene terephthalate) (PETG) and poly(ethylene furanoate) (PEF), were investigated. The morphology of the blends shows a two phase structure in which the minor phase (amorphous polyester) is dispersed as domains in the major (EPDM) continuous matrix phase. Differential calorimetry studies confirmed that both systems were immiscible and exhibits two glass transitions. The melting peak area of EPDM in the blends decreased as the amount of the other component increased. The values of stress at strain of 100% were improved upon the increasing content of PETG in EPDM system, while only slight decrease of this value was observed. Moreover, the strong improvement of hardness and thermo-oxidative stability along with an increasing content of amorphous polyester phase was reported.
