“…The 50 mol% of BHEPS units in the polyester chain makes PBSF and PBSCFs have much higher tensile strength and tensile modulus compared with PBF 30 or PCF 30 and the influence of BHEPS has been studied systematically in our previous work 27 . The notable increase in the elongation at break of PBSCF‐40 is mostly due to the incorporating of CHDM, which has chair‐boat‐chair conformation transition.…”

“…In Figure 1, 1 H-NMR spectra and characteristic peak assignment of PBSCFs were used to identify the chemical structures, our previous works [27][28][29][30] and some related references 34,35 are also referred. It was noted from the enlarged spectrum that the signal for CH (f) in the furan ring split into two overlapping doublets, showing at 7.10-7.13 ppm.…”

The polyesters with high Tg (≥100°C) and good clarity are desired in fabricating heat‐resistance containers such as baby bottles, cups, medical apparatus, and kitchen appliances. In this work, a series of poly(butylene bis[4‐(2‐hydroxyethoxy) phenyl] sulfone 1,4‐cyclohexanedimethylene 2,5‐furandicarboxylate) (PBSCFs) that show superior thermal and mechanical properties against current bio‐based polyesters were synthesized via a melt polycondensation method. The accurate chemical structures of PBSCFs were confirmed by 1H‐NMR and 13C‐NMR. The SEC results show that PBSCFs have number averaged molar mass (Mn) in the range of 9700–28,500 g/mol. The Tg of PBSCFs increase from 94°C for PBSF to 108°C for PBSCF‐50 as the increasing of CHDM unit. Meanwhile, the ductility of PBSCFs also improved with the elongation at break of PBSCF‐40 increased to 223%. In addition, the PBSCF‐40 sample reported in this paper shows thermal decomposition temperature of 427°C, transmittance of 84.6%, haze of only 0.17%, tensile strength of 74.1 MPa, and tensile modulus of 2287 MPa.

“…Polyesters based on FDCA showed a high T g of 98 °C. Liu et al [ 86 ] synthesized a series of novel polyesters with T g higher than 100 °C from FDCA, BDO, and bis [4-(2-hydroxyethoxy) phenyl] sulfone (BHEPS). When the BHEPS content reached 65%, the T g was 104.7 °C with M w of 28,500 g/mol, tensile strength of 82 MPa, and elongation at break of 98%.…”

The big challenge today is the upgrading of sustainable materials to replace miscellaneous ones from petroleum resources. Thus, a generic bio-based building block lays the foundation of the huge bio-market to green economy. 2,5-Furandicarboxylic acid (FDCA), a rigid diacid derived from lignocellulose or fructose, represents a great potential as a contender to terephthalic acid (TPA). Recently, studies on the synthesis, modification, and functionalization of bio-based polyesters based on FDCA have attracted widespread attention. To apply furanic polyesters on engineering plastics, packaging materials, electronics, etc., researchers have extended the properties of basic FDCA-based homo-polyesters by directional copolymerization and composite preparation. This review covers the synthesis and performance of polyesters and composites based on FDCA with emphasis bedded on the thermomechanical, crystallization, barrier properties, and biodegradability. Finally, a summary of what has been achieved and the issues waiting to be addressed of FDCA-based polyester materials are suggested.

“…26,27,33,36 Therefore, it is hard to obtain bio-based TPEEs with satisfactory properties when simply replacing TPA by FDCA. 42−45 To promote the crystallizability of FDCA-derived polyesters, a variety of aliphatic diols, including 2, 2-dimethyl-1,3propanediol, 41,46 butylene glycol, 38,47 hexamethylene glycol, 48 and octylene glycol, 33 expected, the long aliphatic diols could increase their crystallization ability, and the poly(alkyl 2,5-furanoates) synthesized from even carbon diols such as PBF, PHF, POF, and PDeF have better crystallizability than odd carbon diols. 49,50 However, their T m was seriously decreased, which made it hard to meet the thermal resistance requirement.…”

Thermoplastic poly(ester-ether) elastomers (TPEEs) have been applied extensively in automotive components, electrics, medical, and other fields. However, TPEEs with high thermal resistance and shape recovery rate are rarely reported, especially the ones derived from renewable feedstocks. Herein, the renewable 2,5-furandicarboxylic acid (FDCA) and 1,4-cyclohexanedimethanol were taken to construct the hard segment, while poly(tetramethylene glycol) (PTMG) was employed as the soft segment to synthesize poly(ester-ether) elastomers (PCF–PTMG). Investigation showed that PCF–PTMG had excellent thermal resistance with T m up to 254 °C, which was higher than most of the commercial TPEEs. By adjusting the content of the PTMG segment from 30 to 80 wt %, the tensile strength of synthesized TPEEs increased from 31 to 303 MPa and tensile modulus varied in the range of 17 to 27 MPa. More importantly, PCF–PTMG70, containing 70 wt % of the PTMG segment, showed the elongation at break of 676% and shape recovery rate as high as 77.4% during the first cyclic test at 200% strain, which are higher than those of almost all the TPA-based TPEEs. This work indicates that a bio-based FDCA unit has great potential to serve as a highly crystallizable hard segment, as well as PTMG content adjusted the contribution of the soft segments to synthesize the new poly(ester-ether) elastomers with high thermal resistance.
