Supramolecular structure, relaxation behavior and free volume of bio-based poly(butylene 2,5-furandicarboxylate)-block-poly(caprolactone) copolyesters

Abstract

A fully plant-based sustainable copolyester series, poly(butylene 2,5-furandicarboxylate)-block-poly(caprolactone)s, were successfully synthesized by melt polycondensation combining butylene 2,5-furandicarboxylate with polycaprolactone diol at different weight ratios.

Recent Progress on Sustainable 2,5-Furandicarboxylate-Based Polyesters: Properties and Applications

“…As mentioned above, 2,5-FDCA-based polyesters like PEF, PBF, PPF, etc., are closer than ever to replacing traditional or petroleum/fossil-based polyesters like PET, PBT, PPT, etc., because of the large amount of biomass feedstock needed to produce cost-effective, high-tech 2,5-FDCA-based polyesters. ,,,, Currently, biobased 2,5-FDCA polyesters and their copolymers have found their way into industrial applications, from common products to high-performance applications, owing to the advancement of biotechnology and increased public awareness. , But, despite these advances, several drawbacks have hindered the widespread industrialization and commercialization of biobased polyesters for large-scale applications . This is mostly due to cost and performance compared to their traditional counterparts, which remain identical but are still challenging for biobased 2,5-FDCA polyesters …”

“…Additionally, PEF presented excellent gas barrier features in comparison with PET and superior mechanical and thermal resistance, but it exhibited a brittle characteristic at room temperature. Furthermore, various PAFs homopolyesters composed of different aromatic diols were prepared as well, such as poly(butylene 2,5-furandicarboxylate) (PBF), − poly(propylene 2,5-furandicarboxylate) (PPF), ,− poly(nonylene furandicarboxylate) (PNF), ,− poly(hexamethylene 2,5-furandicarboxylate) (PHF), , poly(octylene 2,5-furandicarboxylate) (POF or P8F), poly(1,4-cyclohexanedimethylene furandicarboxylate) (PCF), poly(decylene furandicarboxylate) (PDF), , poly(trimethylene 2,5-furanoate) (PTF), , poly(hexamethylene diglycolate) (PHDG), poly(hexamethylene furanoate) PHF–OH, poly(triethylene furanoate) PTEF–OH, poly(ethylene- co -1,4-cyclohexanedimethylene 2,5-furandicarboxylate) (PECF), , poly(ethylene- co -hexamethylene 2,5-furandicarboxylate) (PEHF), poly(ethylene 2,5-thiophenedicarboxylate) (PETF), poly(ethylene- co -propylene furandicarboxylate) (PEPF), poly(butylene adipate- co -butylene furandicarboxylate) (PBAF), − poly(butylene- co -1,4-cyclohexanedimethylene 2,5-furandicarboxylic acid) (PBCFs), ,, poly(1,4-butanediol 2,5-thiophenedicarboxylate) (PBTF), ,,, poly(decylene 2,5-furandicarboxylate) (PDeF or P10F), poly(dodecylene 2,5-furandicarboxylate) (PDoF or P12F), poly(decylene terephthalate- co -decylene furandicarboxylate) (PDTF), poly(pentylene furandicarboxylate) (PPeF), , poly(propylene 2,5-thiophenedicarboxylate) (PPTF), poly(heptylene furandicarboxylate) (PHepF), poly(hexamethylene 2,5-furandicarboxylate) (PHFC), poly(trimethylene 1,4-cyclohexanedicarboxylate) (PTCE), poly(neopentyl 1,4-cyclohexanedicarboxylate) (PNCE), poly(propylene cyclohexanedicarboxylate) (PPCE),…”

Influence of flexible segment length on the phase structure and properties of poly(hexamethylene 2,5‐furandicarboxylate)‐block‐biopolytetrahydrofuran copolymers

“…Moreover, the direct influence of PPAF incorporation on the overall stiffness of PTF‐based copolymers has been evaluated. On the other hand, several interesting studies have been published on the preparation of PBF‐containing copolymers, for instance with PTMG, 5 poly(ethylene glycol), 37 diglycolic acid, 38 dimerized fatty acids, 39 synthetic low‐molecular‐weight biobased polyester (PBSS), 40 or just recently polycaprolactone (PCL) 41 . Depending on the type and amount of soft segments, some of the above‐mentioned PBF‐based copolymers exhibited the characteristics of thermoplastic elastomers.…”

The influence of the soft segment length on the properties of TPPEs containing FDCA-based polyesters is particularly interesting to us.…”
