Abstract
A process to prepare a polyester polymer composition comprising a polyester polymer having furanic units is disclosed. The process comprises a step of ring-opening polymerization of a cyclic polyester oligomer, which comprises residue of furandicarboxylic acid and a diol, in the presence of a catalyst in order to yield a polyester polymer having furanic units. The polyester polymer composition obtainable by the process, wherein the polyester polymer composition comprises a polyester polymer having furanic units and a cyclic polyester oligomer in a concentration of less than 5 wt % of the composition. The use of the polyester polymer composition in extrusion, injection molding, or blow molding are also disclosed.
