Polyethylene furanoate(PEF) represent a bio-based bioplastic using biomass derived 2,5-furandicarboxylic acid(FDCA). In this study described the synthesis and their characterization of a FDCA-based polyester using various catalysts such as TBT, TIS, Sb2O3 and V2O5 for polymerization of PEF. We investigated the effects 4 kinds of degree of polymerization on PEF catalysts and found that TIS led to the highest Mn of 12000g/mol at the end of melt polycondensation. And as the catalyst content increases from 20 ppm to 100 ppm, the molecular weights of PEF also increase. Additionally, It could be found that the vacuum history in condensation step influence on the molecular weight increase of PEF.
