Title
Understanding of cyclodepolymerization kinetics for the production of cyclic polyethylene furanoate oligomers
Conference Dates
May 20-25, 2018
Abstract
In the last two decades intense research was focused on Polyethylene Furanoate (PEF) as a promising substitute for Polyethylene Terephthalate (PET). Comparisons of PEF and PET material properties revealed improved gas barrier properties, lower melting temperature, as well as higher tensile strength. Together with the reduced carbon foot-print, these properties make PEF an attractive alternative to PET.
Most PEF discussed in the literature is produced by polycondensation reactions (PC), a process, which is intrinsically slow due to diffusion limitations. In fact, it can take up to several days at high temperatures and high vacuum to produce high molecular weight PEF. The long exposure to high temperature is especially detrimental in the PEF case, since PEF is much more prone to thermal degradation than PET.
