A PROCESS FOR PREPARING A POLYMER PRODUCT HAVING A 2,5-FURANDICARBOXYLATE MOIETY WITHIN THE POLYMER BACKBONE TO BE USED IN BOTTLE, FILM OR FIBRE APPLICATIONS.

摘要

The invention relates to a process for preparing a polymer having a 2,5- furandicarboxylate moiety within the polymer backbone, and having a number average molecular weight of at least 25,000, comprising a transesterification step, a polycondensation step, a drying and/or crystallizing step, and a step wherein the polymer is subjected to post condensation conditions, and to a polyester-containing bottle or film or fibre-containing woven or non-woven object made from melt- processing poly(ethylene-2,5-furandicarboxylate), wherein the poly(ethylene-2,5- furandicarboxylate) is obtainable by the process of the invention.
