Abstract: The molecular weight of a semi-crystalline polyester including ethylene 2,5-furandicarboxylate units is increased in a process, including heating the semi-crystalline polyester during a solid state polymerization period. The temperature is at least 180° C. and is kept below the melting point of the semi-crystalline polyester whilst the semi-crystalline polyester is either under a flow of inert gas or under vacuum to obtain a solid state polymerized polyester. The temperature is continuously or periodically increased during the solid state polymerization period.
