“…From the 1 H NMR spectra, the degree of randomness (the probability of finding 1,4 cyclohexane units next to furan units) was found to be proportional to the reaction time, i.e., the block length decreased as the reaction proceeded. Poulopoulou et al simulated reactive blending in DSC pans by heating blends at 20 °C/min and quenching them at −30 °C [ 107 , 108 ]. PEF- co -PPT, PPF- co -PPT, and PEF- co -PBF random copolymers were prepared this way.…”

Polyesters based on 2,5-furandicarboxylic acid (FDCA) are a new class of biobased polymers with enormous interest, both from a scientific and industrial perspective. The commercialization of these polymers is imminent as the pressure for a sustainable economy grows, and extensive worldwide research currently takes place on developing cost-competitive, renewable plastics. The most prevalent method for imparting these polymers with new properties is copolymerization, as many studies have been published over the last few years. This present review aims to summarize the trends in the synthesis of FDCA-based copolymers and to investigate the effectiveness of this approach in transforming them to a more versatile class of materials that could potentially be appropriate for a number of high-end and conventional applications.

“…A very slight shift in the T g values is not enough to indicate significant homogenization ( Figure 3c). Again, from FTIR measurements, the blend retains characteristics of both polyesters, meaning that the C=O stretching at 1742 cm −1 (present in both neat polymers), the angular deformation of aromatic C-H at 830 cm −1 (present in PEF only), terminal hydroxyl groups at 3446 cm −1 (PEF) and the characteristic 2,5-disubstituted furan heterocycles of PEF at 3125 cm −1 (Figure 3d Previous works from our group focused on the study of blends of PEF with PPF or PBF [57][58][59]62]. It was found that the PPF-PEF blends show a single glass transition.…”

“…The third way, that is, blending, is an easy and feasible way for modifying polymer properties. In contrast to the numerous papers on PET blends and on terephthalate polyester blends, only a few papers dealing with furan-based polyester blends have appeared, until now [56][57][58][59].Therefore, in this work, a series of PEF and PPF blends with PEN, PLA, PC, PET as well as PBF and PCDMF were prepared. They were studied concerning their miscibility, crystallization and solid-state characteristics using wide-angle X-ray diffractometry (WAXD), differential scanning calorimetry (DSC) and polarized light microscopy (PLM).…”

Intending to expand the thermo-physical properties of bio-based polymers, furan-based thermoplastic polyesters were synthesized following the melt polycondensation method. The resulting polymers, namely, poly(ethylene 2,5-furandicarboxylate) (PEF), poly(propylene 2,5-furandicarboxylate) (PPF), poly(butylene 2,5-furandicarboxylate) (PBF) and poly(1,4-cyclohexanedimethylene 2,5-furandicarboxylate) (PCHDMF) are used in blends together with various polymers of industrial importance, including poly(ethylene terephthalate) (PET), poly(ethylene 2,6-naphthalate) (PEN), poly(L-lactic acid) (PLA) and polycarbonate (PC). The blends are studied concerning their miscibility, crystallization and solid-state characteristics by using wide-angle X-ray diffractometry (WAXD), differential scanning calorimetry (DSC) and polarized light microscopy (PLM). PEF blends show in general dual glass transitions in the DSC heating traces for the melt quenched samples. Only PPF–PEF blends show a single glass transition and a single melt phase in PLM. PPF forms immiscible blends except with PEF and PBF. PBF forms miscible blends with PCHDMF and PPF, whereas all other blends show dual glass transitions in DSC and phase separation in PLM. PCHDMF–PEF and PEN–PEF blends show two glass transition temperatures, but they shift to intermediate temperature values depending on the composition, indicating some partial miscibility of the polymer pairs.

The block copolymers PEF/PBAT were synthesized by copolymerizing ethylene 2,5-furandicarboxylate (EF) with totally biodegradable poly (butylene adipate-co-terephthalate) (PBAT). The copolymers' molecular chain structure, thermal properties, thermal stability, and mechanical properties were investigated, and the toughening mechanism was preliminarily studied via the micromorphology. The results revealed that the prepared block copolymers were amorphous, the thermal stability of PEF was improved, while the glass transition temperature decreased with the increase of PBAT content. PBAT was enhancing the tensile strength and elongation at break of PEF simultaneously. When the PBAT content was 25% (PEF/PBAT-25), the brittle-ductile transition occurred, with the tensile strength, Young's modulus and elongation at break of 72 MPa, 3210 MPa and 287%, respectively. The copolymers have broad application in the field of packaging materials.
