“…It is worth noting that, unlike previous studies, the enhancement of polarity can lead to a decrease in WCA. 29 As shown in Fig. 6, as compared to the polyester films of PEFT-25 and PEFT-35 obtained by the coating method, the nanofiber films have higher hydrophobicity.…”

“…Jin et al copolymerized THFDM with PET and found that the higher oxygen atom content in THFDM made the polyester less thermally stable with better processability and higher transparency. 29 However, there is still almost no research on the processing of this copolyester. In this paper (Scheme 1), a two-step method was used to copolymerize with THFDM, TPA, and EG as the monomers of copolymerization and C 16 H 36 TiO 4 (TBT) as the catalyst.…”

“…2,5-Tetrahydrofurandimethanol (THFDM) could realize high efficiency conversion from biobased 5-hydroxymethylfurfural (HMF) and large-scale production. More recently, it was successfully introduced into PET and PCF polyesters, as reported by our group, 29,30 resulting in the optimization of properties. Moreover, the copolymerization of THFDM can achieve the aim of introduction of ether groups without sacrificing strength and T g , while the biodegradability of THFDM-based copolyesters still needs further investigation.…”

The problems of fossil-based resources and pollution caused by traditional nondegradable polymers have led to the need for biobased monomers and polyesters, presenting more environmentally friendly features. 2,5-Tetrahydrofurandimethanol (THFDM), a biobased monomer containing an aliphatic ring structure and an ether group, was introduced into the molecular chain of polybutylene succinate (PBS) as a sustainable unit to optimize its performance and improve its sustainability. The poly(butylene-co-tetrahydrofurandimethylene succinate) (PBTS) copolyesters were synthesized using a melt polycondensation method. The copolyesters exhibited relatively high intrinsic viscosity (1.03−1.71 dL/g). The T g values of PBTS copolyesters increased significantly along with the introduction of THFDM (from −32.2 to −12.9 °C). According to the investigation using WAXD (wide-angle X-ray diffraction) analysis and successive selfnucleating annealing (SSA) measurement, it was revealed that the introduction of THFDM reduced the crystallization ability of PBTS while increasing its crystal content with relatively low lamella thickness. This phenomenon was mainly attributed to the aliphatic rings, which limited the movement and regular stacking of the molecular chains. The degradation rate and toughness of the copolyesters improved due to the decrease of crystallization degree. Meanwhile, the gas barrier property of PBTS slightly decreased but remained at a relatively high level. The permeabilities of O 2 and CO 2 were lower than that of commercially available PBAT. In summary, the introduction of THFDM not only improved the biobased resources content and the sustainability of copolyesters but also improved the toughness and degradation performance without sacrificing gas barrier performance.

“…T g of PETG was the highest in this three copolyesters (PETG > PET > PEIT) with maintaining high transparency and great mechanical properties. 12,13 PETG was mainly used in sheet, cosmetic packaging and heat shrinkable films. The reason that IPA and CHDM inhibited crystallization activity was that partially replacing the ethylene glycol (EG) unit in terephthalic acid (TPA) could reduce the unit-regularity of PET.…”

2,5-tetrahydrofurandimethanol (THFDM), which is an alicyclic diol in products of 5-hydroxymethylfurfural (HMF), is a sustainable monomer to protect environment for replacing the role of isophthalic acid (IPA) and 1,4-cyclohexanedimethanol (CHDM) which were optimized polyethylene terephthalate (PET) performance. By direct esterification method, poly (ethylene-co-tetrahydrofurandimethanol terephthalate) (PETT) was synthesized in 2.5 L reactor. The results showed that the contents of THFDM in copolyester were less than that feeding ratio attributed to its lower reaction reactivity. The color of PETT slightly turned yellow. PETT performed broader processing temperature window, while Tg maintained in good range because of the cyclic structure of THFDM. Especially, the cold crystallization occured in PETT but not in PET after finishing melt crystallization. Otherwise, the thermal stability and crystal structure of PETT remained the same as PET. The crystallization activity of PETT became significantly lower than PET. What proved THFDM was effective in reducing PET crystallinity was that crystallization kinetics using Jeziorny theory and the trend of activation energy of melt crystallization which was calculated by Friedman method. And PETT-2 fibre had comparable mechanical property to PET fibre. In the advancement of green chemistry, THFDM has added a choice of cyclic bio-based comonomers.
