“…The size of the partial ionic aggregates was larger than 300 nm, and the number of ionic aggregates decreased as the ionic group concentration increased. The ionic aggregates in this situation may be thought of as larger aggregates composed of many ionic aggregates and PBS chains, which is in accordance with the result obtained by DMA analysis.…”

“…Due to their ease of production, poly(butylene succinate) ionomers have been extensively studied. For example, Lv et al . synthesized a series of PBSIs with different dimethyl‐5‐sulfoisophthalate sodium salt distributions by a chain extension reaction of the dihydroxyl‐terminated PBS precursor and pre‐PBSIs with different ionic group contents.…”

We designed a novel, facile, and mass‐producible strategy for regulating the crystallizing and rheological behaviors of poly(butylene succinate) (PBS) by incorporating segmented PBS urethane ionomers (PBSUI). These macromolecular ionomers contain two segments: one is an ionic enriched segment, which can spontaneously form inter‐ and intramolecular ionic aggregates in PBS to serve as physical crosslinking points to increase the crystallization rate and complex viscosity of the PBS matrix; the other one is a PBS segment, which can improve the compatibility between the PBSUI and PBS matrix. The results from differential scanning calorimetry, polarized optical microscopy, dynamic mechanical analysis, and rotational rheometry suggest that the performance tunability of PBS was easily achieved by adding a very low content of PBSUI (1–5 wt %). PBS containing 3 wt % PBSUI, in which the mass ratio of ionic groups in PBSUI is 7.4%, showed the fastest overall crystallization rate at 12 times faster than PBS to finish crystallization, due to the remarkably increased nucleating efficiency. The dynamic mechanical analysis indicates that for those samples with relatively high ionic concentrations, a cluster of glass‐transition temperatures occurred that was related to an aggregation of PBSUI. The complex viscosity and storage modulus G′ of PBS/PBSUI were also increased, due to the ionic aggregates formed by PBSUI. © 2017 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2018, 135, 45545.

“…In pioneer studies, samples of aromatic sulfonated PBS (PBSS) containing up to 5 mol% of dimethyl 5‐sulfoisophthalate sodium (DMSI) salt have been synthesized via two‐step esterification/polycondensation processes . In these ionomers, the concentration of ionic groups cannot exceed 5 mol%, since DMSI exhibits poor solubility in the reaction mixture .…”

The positional effect of sulfonate groups on poly(butylene succinate) (PBS) microstructure was investigated. In this regard, unsaturated poly(butylene fumarate) (PBF) and poly(butylene succinate‐ran‐fumarate) copolymers, synthesized via esterification/polycondensation reactions, were modified through post‐polymerization modification. The progress of the PBF sulfonation reaction was analyzed via 1H NMR, dynamic light scattering and field emission SEM. The microstructure and thermal behavior of the functional polyesters were studied through DSC, TGA, elemental analysis and 1H NMR. Based on the results, the sulfonation reaction of unsaturated polymer chains, which are not experiencing a phase separation, is instantaneous, but sulfonation of the chains that have formed colloidal particles is a time‐consuming process. Surprisingly, the outcomes of 1H NMR analysis revealed a kind of heterogeneity along the fully sulfonated PBS backbone, similar to what is usually observed for copolymers. This is due to the ability of sulfonate groups to locate in different sites and create various block types. Due to the attraction between sulfonate groups, they tend to attach to the chain such that they provide the greatest number of second type blocks (containing two sulfonate groups). The randomness of sulfonated polymers after the sulfonation reaction was increased compared to that of the corresponding unsaturated copolymers. Increasing the content of sulfonate groups also led to a significant decrease in the thermal resistance (ca 120 °C) and crystallinity, along with a dramatic increase in ash content and Tg (up to 156 °C). © 2018 Society of Chemical Industry

Graphene oxide (GO) was incorporated into poly(butylene succinate) (PBS) via a solution coagulation method to fabricate PBS/GO nanocomposites. Scanning electron microscope and transmission electron microscope observations indicated that GO with very thin layer dispersed in PBS uniformly and showed a good interfacial adhesion with PBS matrix. Differential scanning calorimetry analysis suggested that the crystallization ability of PBS increased first and then decreased with increase in the content of PBS. Isothermal crystallization kinetics investigation manifested that the overall crystallization rate of PBS increased first and then decreased with increasing PBS content while the crystallization mechanism remained unchanged. Polarized optical microscopy analysis indicated that GO worked as an effective nucleating agent for PBS. X-ray diffraction characterization suggested that incorporation of GO did not change the crystal structure of PBS. Both tensile testing and dynamic mechanical analysis witnessed the reinforcement in mechanical performance of PBS by incorporation of GO.
