Abstract:
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.

Claim (Index 6):
The process according to  claim 1 , wherein the esterification step is carried out at a temperature of 160 to 240\u00b0 C. and a pressure of 0.9 to 5 bar for a period of 0.5 to 5 hr.
