“…According to the viscosity curve, intrinsic viscosity was a little greater in xylene ([η] P(SA)xylène = 7.1 10 −3 ± 1 10 −5 L/g) than in THF ([η] P(SA)THF = 10 −4 ± 5 10 −5 L/g). According to Abed et al,26 the lower the polarity of solvent, the stronger the hydrogen bonding. Thus, according to the authors, solvent polarity influences the oligomers viscosity.…”

Polyanhydrides are largely used in biomedical and pharmaceutical fields because of their biodegradability and controlled degradation. In this work, oligomers were investigated as film binders for environmental applications. To overcome the main disadvantages of polyanhydrides (low solubility in common solvents and high melting points), oligomers based on sebacic acid were prepared. Characterization was carried out by nuclear magnetic resonance and electrospray ionization to obtain chemical structures of the products. The formation of weak interactions, which confer cohesion between chains, allows film properties to be observed. The impact of the solvent polarity on the specific organization was investigated by a combination of focused methods: capillary viscosimetry, IR spectroscopy, polarized light microscopy, and X-ray diffraction.

“…Molar mass of polymers can be deduced from intrinsic viscosity measurement through a Mark-Houwink calibration curve. This approach can be applied to supramolecular polymers if Mark-Houwink and Huggins parameters are known [192]. However, finding a suitable covalent model to estimate these coefficients is a difficult task.…”

“…Pioneering advances by Lehn16–18 have stimulated the development of supramolecular polymers which offer very attractive potential for stress‐ and temperature‐induced self‐repair resulting from cleavage and reassembly of non‐covalent bonds, especially of donor/acceptor moieties containing hydrogen bridges 19–21. This concept has been applied to reactive oligomers and elastomers by the groups of Meijer and co‐workers,22–25 Bouteiller and co‐workers26 and by Leibler and co‐workers 27. New families of self‐healing supramolecular elastomers have evolved.…”

Hyperbranched PEI and urea‐functionalized PEI amphiphiles are employed as additives in NBR compounding. Polarity design governing phase separation, PEI migration and PEI‐mediated self‐healing of NBR is demonstrated. The compatibility of PEI and NBR decreases with increasing molecular weight of PEI and with decreasing degree of substitution. Microphase‐separated NBR/PEI blends are prepared with varying PEI molecular architectures. Thermal self‐healing of NBR/PEI is monitored by applying tests combining crack initiation with annealing under compression. All PEI additives show complete crack‐healing upon annealing at 100 °C for 12 h. In contrast to neat NBR, the NBR/PEI‐2 blend afforded a self‐healing efficiency of 44% after cutting and re‐joining by compression and annealing.
