“…For example, absorption peaks at 1740 cm −1 and 1723 cm −1 originating from carbonyl absorption in amorphous and crystalline component, respectively, had been distinguished for PHBV . A more similar example to PBSA is the case of PBS, whose amorphous and crystalline carbonyl absorption being identified at 1738 cm −1 and 1722 cm −1 , respectively . Therefore, for PBSA with only 5 mol% of BA unit in this work, the shoulder peak at higher wavenumber (1737 cm −1 ) and the most obvious peak at lower wavernumber (1716 cm −1 ) are assigned to stretching vibration of carbonyl in amorphous and crystalline component, respectively.…”

“…Some low molecular weight dihydric phenols can be used as antioxidants and thermal stabilizer in polymer processing, which also have been reported to have the capability to form hydrogen bonding interaction with polyesters owing to electrophilic hydroxyl groups in molecular structure. Moreover, the mobility of dihydric phenols and the dynamic character of hydrogen bonding motivated researchers to investigate the impacts of incorporation of dihydric phenols on properties of polyesters, For instance, a series of dihydric phenols including TDP, bisphenol A (BPA), 4,4′‐dihydroxydiphenyl mechane (DHDPM) and 4,4′‐dihydroxydiphenyl ether (DHDPE) had been incorporated into PBS, PCL, poly (3‐hydroxybutyrate‐ co ‐3‐hydroxyvalerate) (PHBV), Poly (3‐hydroxybutyrate), poly (L‐lactic acid), etc . The crystallization behavior and morphologies of the polyesters were modified as a result of hydrogen bonding network, and some novel properties were obtained.…”

The poly (butylene succinate-co-butylene adipate) (PBSA)/thiodiphenol (TDP) complexes were prepared by melt blending. Intermolecular hydrogen bonding between carbonyl group of PBSA and hydroxyl group of TDP formed as verified by a combination FTIR and peak fitting technique. As a result, the crystallization temperature, melting temperature, crystallinity and crystallization rate of PBSA decreased with addition of TDP, implying impeded crystallization and reduced lamellar thickness. On the basis of Lauritzen-Hoffman analysis, the fold surface energy (σ e ) and work of chain folding (q) were increased by TDP incorporation. POM observation exhibited concentric ringbanded spherulites for samples with 10 and 20 wt% TDP. A peculiar ring-banded pattern with discrepant band spacing was obtained for the first time by addition of 30 wt% TDP, whose formation mechanism remains to be discussed.

“…40 In contrast, Luo et al attributed the 1713 cm −1 band in PBS/ bisphenol blends to the CO groups hydrogen-bonding with −OH groups of bisphenol. 32 When we tried to summarize the law of FTIR absorption bands for CO groups in PBS, some puzzling results, however, emerged. Although the absorption band around 1736 cm −1 has been consistently assigned to C O groups in amorphous PBS, the corresponding band position for crystalline phase has been proposed in a wide range from 1728 to 1709 cm −1 in different studies.…”

The detailed structure and crystallization behavior of poly(butylene succinate) (PBS) have been investigated by Fourier transform infrared (FTIR) and other methods systematically. For the first time, we confirmed that the C═O stretching modes of PBS can respond to three distinguish absorption bands in the FTIR spectrum, at around 1736, 1720, and 1714 cm respectively. The 1736 cm band is adopted as the stretching mode of C═O groups in free amorphous fraction (MAF); the 1714 cm band which is relevant to more stable structure, displays more anisotropic in polarized FTIR spectra, and has been confirmed as stretching vibrations of hydrogen-bonded C═O groups in the crystalline phase. The 1720 cm band is linked to crystallization but comes from less ordered structure. Moreover, the 1720 cm band can be destroyed prior to 1714 cm band during heating and constructed behind 1714 cm band during cooling. Thus, the 1720 cm band is reasonably ascribed to the C═O groups in rigid amorphous fraction (RAF) or intermediate phase which locates between MAF and crystalline phase. The corresponding investigation by differential scanning calorimetry (DSC) and wide-angle X-ray diffraction (WAXD) further supports that the three particular C═O absorption bands indeed reveal the typical three-phase structure for PBS. More important, the FTIR spectrum of PBS is very sensitive to sample preparation process and measurement mode. The relative content of each band depends on the crystallization temperature (T) and measured thickness. The higher T, the more RAF content appears when measured at room temperature; the thinner penetration thickness of FTIR measurement, the less RAF content can be detected, and the penetration thickness-dependent behavior is suggested as the result of higher mobility of chains in the air/bulk surface. Additionally, the particular three absorption bands of C═O groups in PBS force us to carefully reconsider previous reports on structure and interaction state obtained by FTIR spectroscopy in PBS and its composites.

“…Bisphenol, endowing the same dihydroxyl-terminal structure as diols, can serve as a substitution of diol to react with diacid. As a result, it was often used to mediate the crystallization behaviors and physical properties of polyesters, such as polybutylene terephthalate (PBT) [ 35 ], polybutylene succinate (PBS) [ 36 ], polycaprolactone (PCL) [ 37 ] and so on. In previous study, the overall isothermal crystallization rate and growth rate of spherulites of PBS were depressed by bisphenol A [ 36 ].…”

Crystallization and Thermal Behaviors of Poly(ethylene terephthalate)/Bisphenols Complexes through Melt Post-Polycondensation

et al. 2020

Three kinds of modified poly(ethylene terephthalate) (PET) were prepared by solution blending combined with melt post-polycondensation, using 4,4′-thiodiphenol (TDP), 4,4′-oxydiphenol (ODP) and hydroquinone (HQ) as the bisphenols, respectively. The effects of TDP, ODP and HQ on melt post-polycondensation process and crystallization kinetics, melting behaviors, crystallinity and thermal stability of PET/bisphenols complexes were investigated in detail. Excellent chain growth of PET could be achieved by addition of 1 wt% bisphenols, but intrinsic viscosity of modified PET decreased with further bisphenols content. Intermolecular hydrogen bonding between carbonyl groups of PET and hydroxyl groups of bisphenols were verified by Fourier transform infrared spectroscopy. Compare to pure PET, both the crystallization rate and melting temperatures of PET/bisphenols complexes were reduced obviously, suggesting an impeded crystallization and reduced lamellar thickness. Moreover, the structural difference between TDP, ODP and HQ played an important role on crystallization kinetics. It was proposed that the crystallization rate of TDP modified PET was reduced significantly due to the larger amount of rigid benzene ring and larger polarity than that of PET with ODP or HQ. X-ray diffraction results showed that the crystalline structure of PET did not change from the incorporation of bisphenols, but crystallinity of PET decreased with increasing bisphenols content. Thermal stability of modified PET declined slightly, which was hardly affected by the molecular structure of bisphenols.
