Fossil-free Furan-based Thermoplastics as PET Alternative

Biobased furfural derived bifuran containing monomers with efficient oxygen and UV barrier

Background

Urgent need to replace fossil-based products, such as plastics, with carbon neutral biobased materials has shown notable increase during the recent years. Well-known biobased solutions such as cellulose-derived materials and polylactic acid (PLA) are useful in certain applications. However, it is highly challenging to replace traditional fossil-based thermoplastics such as polyethylene terephthalate (PET) due to differences between materials properties e.g. processability, moisture sensitivity (cellulose-based materials) or worse oxygen barrier capability (PLA). Unfortunately, it is extremely difficult to prepare PET from biobased raw materials. Mostly, the biocarbon content is restricted to 20% that is achieved by utilizing biobased ethylene glycol as a diol unit in polymer manufacturing. 5-Hydroxymethylfurfural (HMF) based polyethylene furanoate (PEF) with 100% biobased carbon content has been
