Nonisothermal Crystallization of Biobased Poly(ethylene 2,5-furandicarboxylate)

摘要

The production of fuels, chemicals and polymers from biomass feedstocks allows to moderate our dependence on finite oil resources. However, scientific and technical barriers still exist to get sustainable market implementation of novel bio-based products. Poly(ethylene terephthalate) (PET) is a well-known aromatic polyester issued from the polycondensation of Terephthalic Acid (TA) with ethylene glycol. The PET success story is explained by its outstanding barrier properties coupled with recyclability and rather easy processing. A bio- based alternative to PET should therefore feature similar or improved material properties for its main applications, such as thermo- mechanical and barrier properties, crystallization kinetics, color, etc. In the past few years, intensive progress have been made in the industrial production of 5-hydroxymethylfurfural (HMF) from C6 sugars contained in biomass feedstocks. [1] The HMF is an aromatic key-platform chemical that can be further converted in 2,5-furandicarboxylic acid (FDCA) which can be considered as the bio-analogue of TA.
