摘要： A process to prepare a cyclic polyester oligomer composition comprising a cyclic polyester oligomer having furanic units is disclosed. The process comprises the step of reacting a monomer component in a ring closing oligomerization step carried out in the presence of a solvent by means of reactive distillation. Linear oligomeric polyester species are separated and removed by one or more sub-steps of adding a zeolite and absorbing impurities onto the zeolite, separating the zeolite having absorbed impurities, cooling the cyclic oligomeric composition and/or adding an anti-solvent in order to precipitate out the cyclic polyester oligomers. The invention further relates to a cyclic polyester oligomer composition obtainable by said process and also to its use in the production of a polyester polymer, particularly by polymerization in the presence of a plasticizer, as well as the polyester polymer obtained thereby.

The invention relates also to the use of a 2,5-FDCA compound selected from 2,5-furandicarboxylic acid (2,5-FDCA) and esters thereof as an anti-crystallization comonomer in a PET polymer. The invention relates also to a bio-based PET polymer in which the anti-crystallisation comonomer is bio-based.

摘要： A polyester including ethylene 2,5-furandicarboxylate units is prepared in a process, where in an esterification step a 2,5-furandicarboxylate compound is reacted with ethylene glycol to form an ester composition, including components with 2-hydroxyethyl and 2,5-furandicarboxylate moieties; where in a polycondensation step the ester composition thus obtained is subjected to polycondensation at reduced pressure in the presence of a polycondensation catalyst to obtain a polycondensate; and where during the polycondensation step 2,5-furandicarboxylic acid is added to the ester composition.
