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

In this investigation, a series of novel random bio-based thiophene–aromatic copolyesters, including thiophene and phenyl units, were successfully prepared from dimethyl 2,5-thiophenedicarboxylate, dimethyl 2,5-dimethoxyterephthalate, and the aliphatic diols ethylene glycol, 1,3-propanediol, 1,4-but...

A study of structure-property relations showed that the properties of these copolymers can be tailored by varying their composition. All the copolyesters exhibited high tensile strength (45–80 MPa) and toughness values (elongation at break of 200–540%). After 28 weeks of incubation in humid soil, weight losses of up to 7.2% were observed. Considering their good mechanical properties, thermal stability and biodegradability, these renewable sulfur-containing copolyesters have great potential to replace petroleum-based commercial poly(ethylene terephthalate) in the food packaging industry, which is helpful to implement carbon neutrality and sustainable development in the polymer industry.Lesly Dasilva Wandji DjouonkepZhengzai ChengWilliam Mawuko Kodjo SieguXiong JingJun ChenElvis Kwame AdomAbubakar MuazMario GauthierBudapest University of Technology articlebiodegradable polymersaromatic monomersaliphatic diolsmechanical propertiesmelt transesterificationMaterials of engineering and construction.
