Abstract: 2,5-Furan dicarboxylate polyesters (FDCA polyesters) are bio-based polymers prepared by
2,5-furandicarboxylic acid which derived from renewable resources as mainly intermediate. In this review,
the research progress of FDCA polyesters is introduced. The performances, synthetic methods, catalysts and
copolymerization modification of FDCA polyesters are discussed. The glass transition temperatures (T g),
thermal stabilities, Young's modulus and tensile strength of FDCA polyesters are similar to those of
terephthalic acid (PTA) polyesters. FDCA polyesters also possess better CO 2, O 2 and H 2O gas barrier
properties than PTA polyesters. FDCA polyesters have recently gained high interests due to their excellent
properties, and may be potential substitutes of PTA polyesters in many fields. However, FDCA polyesters
lack of toughness, which significantly hinders their industry applications. Copolymerization is one of the
effective methods to improve the mechanical properties of FDCA polyesters. In most cases, the copolymer's
elongations enhance, however, the Young's modulus and T g decline rapidly simultaneously. It is still a
challenge and one of the most important subjects in FDCA copolymers to improve the elongations at break
and achieve a higher Young's modulus and a higher T g at the same time.
