“…Novel approaches of the preparation of HMF lead in the large-scale production of FDCA [14] and thus enable to increase the production of polyesters bearing furan moieties like PEF [15], poly(butylene 2,5-furan dicarboxylate) (PBF) [16], that one can seriously regard as the biobased alternatives of terephthalates. Additionally, the successful production of PEF thin films and a comparison of the enzymatic hydrolysis of PEF and PET films have been reported by Weinberger et al [17]. Similarly, one can find it for other thermoplastic polyesters, namely poly(trimethylene terephthalate) (PTT) and its furan homologue, i.e.…”

The purpose of this study was to enhance the glass-transition temperature of poly(butylene 2,5-thiophenedicarboxylate) (PBTF). A series of poly(butylene-co-1,4-cyclohexanedimethylene 2,5-thiophenedicarboxylate)s (PBCTFs) were synthesized from 2,5-thiophenedicarboxylic acid, 1,4-cyclohexanedimethanol (CHDM), and 1,4-butanediol. CHDM can increase the chain rigidity and lead the β relaxation temperature shift to lower temperature. Consequently, PBCTFs showed not only the high glass-transition temperature, but also high elongations at break. PBTF was a crystalline polyester. However, differential scanning calorimetry and wide-angle Xray diffraction results suggested PBCTFs were amorphous polyesters. Thermogravimetric analysis results indicated the thermal stability of copolyesters was gradually enhanced with increasing the CHDM content. When the CHDM content was 95 mol %, PBCTF95 exhibited high glass-transition temperature (69.2 C), tensile strength (44.4 MPa), and elongation at break (205%).

“…This enzyme was selected from among the variety of hydrolases available in our laboratory since it had previously been reported to hydrolyze both aliphatic poly(lactic acid) and poly(butylene succinate) (PLA, PBS) [13,29] and aromatic (PET, PEF) polyesters [30,31]. Figure 1 shows the time course hydrolysis reaction of the four different powders.…”

Poly(ethylene 2,5-furanoate) (PEF) is arousing great interest as a biobased alternative to plastics like poly(ethylene terephthalate) (PET) due to its wide range of potential applications, such as food and beverage packaging, clothing, and in the car industry. In the present study, the hydrolysis of PEF powders of different molecular masses (M n = 55, M w = 104 kg/mol and M n = 18, M w = 29 kg/mol) and various particle sizes (180 < d and 180 < d < 425 µm) using cutinase 1 from Thermobifida cellulosilytica (Thc_cut1) was studied. Thereby, the effects of molecular mass, particle size and crystallinity on enzymatic hydrolysis were investigated. The results show that particles with lower molecular mass are hydrolyzed faster than those with higher masses, and that the higher the molecular mass, the lower the influence of the particle size on the hydrolysis. Furthermore, cutinases from Humicola insolens (HiC) and Thc_cut1 were compared with regard to their hydrolytic activity on amorphous PEF films (measured as release of 2,5-furandicarboxylic acid (FDCA) and weight loss) in different reaction media (1 M KPO pH 8, 0.1 M Tris-HCl pH 7) and at different temperatures (50 • C and 65 • C). A 100% hydrolysis of the PEF films was achieved after only 72 h of incubation with a HiC in 1 M KPO pH 8 at 65 • C. Moreover, the hydrolysis reaction was monitored by LC/TOF-MS analysis of the released reaction products and by Scanning Electron Microscopy (SEM) examination of the polymer surfaces. Enzymatic hydrolysis of PEF with Thc_cut1 and HiC has potential for use in surface functionalization and recycling purposes.
