We report the multifunction of FDCA to influence the esterification reaction kinetics and the depolymerization kinetics ( via alkaline hydrolysis) of the copolyester PETF.
WebPEF can undergo methanolysis to recover back its monomers at a much faster rate than PET. 170 The chemical glycolysis of PEF was examined as an EoL option with the use of … WebPoly(ethylene furanoate) (PEF) is widely advocated as a renewable alternative to the fossil-based polyester poly(ethylene terephthalate) (PET). Whereas the UV stability of PET is well-studied, little is known for PEF. Here, we compare the UV stability of both polyesters after 500 h of UV irradiation in a Q-SUN xenon arc chamber.
