In this case, TPU has been synthesized in a classic two-step protocol and obtained from different potentially sustainable building blocks (PTHF, MDI and BDM). A long polyether polyol PTHF (2000 g mol -1 ) was used. PTHF can be synthesized from THF, itself produced from BDO which can be derived from sustainable resources such as biomass or by chemical and/or enzymatic depolymerization at end-of-life of polymers such as PU, PBS or PBAT . BDM can be obtained by hydrogenolysis of PET or poly(butylene terephthalate) (PBT) . MDI can be produced from aniline derived from sugarcane . Thermal properties (TGA and DSC) of the synthesized TPU are given in Table .
