“…It is due to the improved flexibility of the macromolecules by much more elastic PEO segments' distribution, but also a specific microstructure formed. Such effects have been already observed for the PBF block copolymers with poly(tetramethylene glycol) [15] or dimerized fatty acids [17], and the mechanical parameters, namely, the tensile strength and elongation at break of the PBF-PEO 1000 samples are comparable to the results reported in [19]. The character of deformation is also changing with the PEO segment content in both series of the copolymers, whereas the effect of the flexible segment length is mainly pronounced by the differences in elongation at break values.…”

“…Considering crystallizability of PBF, Papageorgiou et al reported that during cooling from melt PBF crystallizes within the temperature range of 150 to 60 • C, depending on cooling rate, with high nucleation density, and the same temperature range was observed for the cold crystallization effect during subsequent heating [14]. The effect of phase separation in the microstructure and a significant modification of the mechanical behavior towards elastomers was observed in several studies, in which PBF was used as the rigid segment, while the flexible segment was poly (tetramethylene glycol) (PTMG) [15] (analogous to commercially available PBT/PTMG), diglycolate [16], or dimerized fatty acids [17].…”

Microstructure and Mechanical/Elastic Performance of Biobased Poly (Butylene Furanoate)–Block–Poly (Ethylene Oxide) Copolymers: Effect of the Flexible Segment Length

et al. 2020

The aim of this paper is to extend knowledge on biobased poly(butylene furanoate)–block–poly (ethylene oxide) (PBF-b-PEO) copolymers’ performance by studying the effect of the PEO segment’s molecular weight on the microstructure and materials behavior. As crystallization ability of PEO depends on its molecular weight, the idea was to use two PEO segment lengths, expecting that the longer one would be able to crystallize affecting the phase separation in copolymers, thus affecting their mechanical performance, including elasticity. Two series of PBF-block-PEOs with the PEO segments of 1000 and 2000 g/mol and different PBF/PEO segment ratios were synthesized by polycondensation in melt, injection molded to confirm their processability, and subjected to characterization by NMR, FTIR, DSC, DMTA, WAXS, TGA, and mechanical parameters. Indeed, the PEO2000 segment not only supported the crystallization of the PBF segments in copolymers, but at contents at least 50 wt % is getting crystallizable in the low temperature range, which results in the microstructure development and affects the mechanical properties. While the improvement in the phase separation slightly reduces the copolymers’ ability to deformation, it is beneficial for the elastic recovery of the materials. The investigations were performed on the injection molded samples reflecting the macroscopic properties of the bulk materials.

“…These values are smaller than those reported in the literature for PBF samples, for which high mechanical properties were measured such as Young's modulus about 964 ± 37 MPa, elongation at break 1108% ± 108%, and tensile strength at break 32.9 ± 5.2 MPa . Similar properties for PBF like Young's modulus of 875 ± 18 MPa and tensile strength at break of 35 ± 2.6 MPa have also been reported from Zhou et al, except the elongation at break which was very low, about 55% ± 10%. Wu et al reported much higher mechanical properties for PBF: Young's modulus 1860 ± 160 MPa, tensile strength at break 55.6 ± 1.6 MPa, and elongation at break 256% ± 19%.…”

In this study, biobased furan dicarboxylate polyesters have been prepared using 2,5‐furandicarboxylic acid (FDCA) and diols with high number of methylene groups (long‐chain diols), namely, 8, 9, 10, and 12. Because of the high boiling points of these diols, a modified procedure of the well‐known melt polycondensation was applied in this work. According to this, the dimethyl ester of FDCA (DMFD) reacted in the first transesterification stage with the corresponding diols forming bis‐hydroxy‐alkylene furan dicarboxylates (BHFD). In the second stage, the BHFD reacted with DMFD again at temperatures of 150–170 °C (for 4–5 h), and in the final stage, the temperature was raised to 210–230 °C (vacuum was applied for 2–3 h). The molecular weight of the polyesters and the content of oligomers, as was verified by gel permeation chromatography analysis, depend on the polycondensation time and temperature. The chemical structure of the polyesters was verified from 1H NMR spectroscopy. All the polymers were found to be semicrystalline, with melting temperatures from 69 to 140 °C depending on the diol used. In addition, the mechanical properties also varied with the type of diol. The higher values were observed for poly(octylene 2,5‐furanoate), whereas the lowest values were observed for poly(dodecylene 2,5‐furanoate) with the higher number of methylene groups in its repeating unit. © 2015 Wiley Periodicals, Inc.

“…Thermal and mechanical properties of this randomly distributed multi-blocked copolyester were governed by PTF to FADD ratio [18]. Similarly, butylene 2,5-furandicarboxylate units substituted their terephthalate counterparts to serve as a bio-based hard segments for elastomer [19]. The biodegradability is another advantage which can be achieved by introducing suitable aliphatic comono mers to the aromatic polyester elastomer [20].…”

Abstract.A new bio-based elastomer, poly(butylene 2,5-furandicarboxylate-ε-caprolactone) (PBFCL), has been synthesized from 2,5-furandicarboxylic acid, 1,4-butanediol, and ε-caprolactone successfully for the first time. The obtained copolyester was characterized in terms of chemical structure, thermal and mechanical properties, and enzymatic degradability. In PBFCL elastomer, butylene-2,5-furandiacrboxylate units (hard segments) crystallize to serve as physical crosslinks while ε-caprolactone polyester diol (soft segments) provide flexibility. PBFCL is a multi-blocked copolyester with randomly distributed rigid and soft segments. It possesses original feature of high strength and biodegradability stemming from the uses of aromatic and aliphatic monomers respectively. An important aspect of this new furanic-aliphatic polyester is its tailor-made properties simply achieved by changing the content of hard or soft segments. Typically, PBFCL-40 of optimal composition has Young's modulus as low as 15.4 MPa, tensile strength as high 24.8 MPa, and elongation as long as 885%.
