Poly(ethylene 2,5-furandicarboxylate) (PEF) is nowadays considered as a promising sustainable successor of poly(ethylene
terephthalate) (PET) for several reasons. First, the PEF is fully biobased since it comes from the polycondensation of biobased
ethylene glycol and 2,5-furandicarboxylic acid (FDCA) which is the chemical analogue of the terephthalic acid. FDCA is
currently a.o. produced at pilot plant scale by a C6 sugars conversion process of vegetable biomass by Avantium. PEF possesses
superior barrier properties and more attractive thermal properties (e.g., higher glass transition temperature and lower melting
point) than PET. The much lower CO2, O2 and H2O permeability of PEF is a tremendous advantage for packaging applications.
In order to fill the requirements of industrial applications, a deep knowledge of polymer structure-property relations is
needed and will be the subject of this presentation. An important aspect for both the production and application of aromatic
polyesters such as PEF is their crystallization behavior. Drying and solid state polymerization processes, that are common for
polyesters, occur above Tg and require the material to be semi-crystalline to avoid massive agglomeration or sticking. This is
initially achieved by quiescent crystallization of the polyester. PEF crystals either formed from the glass or from the melt show
similar structures but the dynamic of crystal growth differs between the two crystallization pathways. Moreover, annealing at
temperatures close to the PEF melting point allowed obtaining information on PEF self-nucleation behavior.
Nathanael Guigo received his PhD in 2008 from the University of Nice Sophia Antipolis, France in the field of Furanic Based Polymers. He joined the Centre de Recherche sur les Macromolécules Végétales, Grenoble, France as a Post-doctoral Fellow to work on cellulosic fibers in high performance composites. In 2010, he became Associate Professor and in 2013, he obtained a secondment to Avantium (Amsterdam) to work on the poly(ethylene 2,5-furandicarboxylate). His scientific work has been published in more than 25 papers and he has been actively involved in three EU projects relative to the valorization of biomass into new materials.
