“…However, when the subsequent heating scans are analyzed, the cold crystallization peaks are easily detected for all samples, as well as the melting and glass transition effects, which confirms the semicrystalline nature of the copolymers (Figure 4b). These observations are contrary to the crystallization results reported by Hu [19], where an incorporation of PEO1000 segments supported the melt crystallization process in all investigated copolymers, but correspond to the FSC studies by Sousa [18]. It was concluded that the PBF/PEO copolymers' crystallization rate is slower than that of the neat PBF, and no crystallization or melting peaks were observed for varied cooling rates.…”

“…As seen in Table 1 the integral intensities of signals d (I d ) and e (I e ), corresponding to the presence of the flexible segment, are changing the most due to their different content in copolymers. The obtained results strictly correspond to the 1 H-NMR results reported for the similar PBF/PEO or PBF/PPO copolymers [18][19][20]. The calculated real contents of the rigid and flexible units are also very close to those theoretically calculated, what confirms once again the expected segmented structure of the copolymers.…”

“…The intrinsic viscosity numbers [η], determined at 30 • C, were: 0.87 for the homopolymer, and 0.97 to 1.27 dL/g for copolymers with increasing PEO content, regardless its molecular weight. These values correspond to the results reported in [19]. Moreover, the materials were characterized by the following molecular weights (M n ), i.e., 34,100 for PBF homopolymer (Ð = 1.8) as well as 56,400 (Ð = 1.9) and 69,000 (Ð = 2.0) for PBF-PEO 1000 50 and PBF-PEO 2000 50 samples, respectively.…”

“…Concurrently, the glass transition effects of PBF amorphous phase were not detectable on DSC thermograms. Significantly different thermal parameters were reported by Hu et al for PBF/PEO copolymers with 10 to 60 wt % of PEO [19]. For this series of materials, the T m values decreased gradually from 167 to ca.…”

“…Recently a few studies on PBF block copolymers have been published, in which poly (ethylene oxide) (PEO) or poly (propylene oxide) (PPO) were used as the co-monomers [18][19][20]. The special interest in these building blocks lies in their non-toxicity and biocompatibility [21], that extends the potential applications of the biobased copolymers also for biomedical purposes.…”

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

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.

A series of multiblock copolymers poly(ethylene terephthalate)-co-poly(ethylene glycol)-poly(propylene glycol)-poly(ethylene glycol) (PET-X%-E-P-E) were synthesized from dimethyl terephthalate (DMT), ethylene glycol (EG) and poly(ethylene glycol)-poly(propylene glycol)-poly(ethylene glycol) (E-P-E) with a two-step procedure via melt polymerization. The structure, composition, crystallization behavior, and thermal stability of the synthesized copolymers were determined by 1 H-NMR, FT-IR, XRD, DSC, and TGA measurements. All samples exhibited good thermal stability at a T d-5% above 300 C. DSC results revealed an increment trend of crystallization ability of copolymers in lower E-P-E content and then decreased when E-P-E concentration gradually raised to 40 wt%. Furthermore, the mechanical properties of copolymers were investigated systematically; the incorporation with E-P-E segments significantly enhanced the toughness and water absorption ability. Impact strength increased from 670.46 to 4448.75 J/m 2 , and water absorption values raised from 0.7% to 3.4% of the content of E-P-E increased. The stress-strain curve exhibited that tensile strength reduced from 40.38 to 17.88 MPa, the elongation at break increased from 4.6 to 27.9%. These new tough PET materials have an important application in toughness polyester fiber by the melt-spinning techniques.

In this work, we prepared a series of bio‐based poly(butylene adipate‐co‐furandicarboxylate) (PBAF) copolyesters with BF segments ranging from 20 to 80 mol% through a two‐step polycondensation. Then, their thermal, mechanical, gas barrier, and degradable properties were investigated. With the increase of BF content, the glass transition temperatures (Tg) and melting temperatures (Tm) of PBAFs increase constantly. Besides, PBAF copolyesters exhibit excellent mechanical performance with elongation at break in the range of 140% to 870%. The elastic modulus and tensile strength of PBAF60 are 138 and 17 MPa respectively, which are comparable to those of commercial poly(butylene adipate‐co‐terephthalate) (PBAT). Moreover, thanks to the structural characteristics of the furan ring, the barrier performances against CO2, O2, and H2O of PBAFs are 4.6–147.5 folds, 4.0–76.0 folds, and 0.8–8.7 folds of PBAT, respectively. Finally, the degradation tests reveal that the weight losses of PBAFs increase with decreasing BF contents. It is worth emphasizing that although the compost degradation rate of PBAF60 is slightly lower than that of PBAT, it is still a prospective alternative to PBAT due to its improved barrier properties. And it provides a possibility for applications in food packaging, mulch films, and structural elements.
