Synthesis and characterization of bio-based polyesters from 2,5-thiophenedicarboxylic acid

Poly(Alkylene 2,5-Thiophenedicarboxylate) Polyesters: A New Class of Bio-Based High-Performance Polymers for Sustainable Packaging

“…The PHTF profile was characterised by well-defined peaks identified at 6.5°, 19.2°, 20.0°, 22.6°, 24.9°, 28.6° and 31.3°, indicating the presence of a conspicuous amount of crystals. This pattern is compatible with the one reported by authors of another study [ 19 ].…”

“…In addition, 2,5-TDCA can be derived from renewable sources and is already industrially produced from adipic acid, which can be obtained, in turn, from glucaric acid, muconic acid, or lignin [ 11 , 12 , 13 , 14 ]. As proof of the growing interest in these polyesters, many scientific studies have been recently published, including those conducted outside of our research group, demonstrating the great potential of both thiophene-based homopolymers and copolymeric systems [ 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 ].…”

High performance sulfur-containing copolyesters from bio-sourced aromatic monomers

“…These polyesters also displayed good biodegradability, allowing them to decompose in a natural environment after their life cycle is completed, due to the presence of C-S bonds sensitive to relatively abundant strains of sulfur-loving bacteria and other microorganisms in the soil. 2,5-Thiophenedicarboxylic acid (TDCA) is a stable thiophene derivative that can be synthesized from sugars, a renewable resource, even though that monomer is currently derived from adipic acid and thionyl chloride [24] (Figure 1a). TDCA and terephthalic acid are similar in that they both contain conjugated ring structures.…”

High Tg and tough poly(butylene 2,5‐thiophenedicarboxylate‐co‐1,4‐cyclohexanedimethylene 2,5‐thiophenedicarboxylate)s: Synthesis and characterization

“…Nowadays, many studies about bio‐based polymers have begun in the last decade due to an increasing environmental awareness and the depletion of oil resources . Specially, sustainable materials with high‐performance or biodegradability have become the research hot spot, such as poly(ethylene 2,5‐furandicarboxylate) (PEF), poly(1,4‐butylene 2,5‐furandicarboxylate), poly(lactic acid), and poly(butylene 2,5‐thiophenedicarboxylate) (PBTF) …”
