Abstract
A polyethylene terephthalate (PET) polymer having diacid units derived from diacid compounds, said diacid units comprising: a) from 92.50 mol % to 97.75 mol % of terephthalic units derived from terephthalic acid (TA) or an ester thereof, and b) from 2.25 mol % to 7.50 mol % of 2,5-FDCA units derived from 2,5- furandicarboxylic acid (2,5-FDCA) or an ester thereof, and-diol units derived from diol compound(s), the diol units having monoethylene glycol units derived from monoethylene glycol (MEG), as well as to a method to prepare a PET polymer. 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 and a bio-based PET polymer in which the anti-crystallisation comonomer is bio-based.
