“…A second-generation hyperbranched polyester polyol with terminal carboxylic group BH20 -COOH was prepared by the esterification of hyperbranched polyester polyol Boltorn H20 (16 hydroxyl groups, M r = 1749.79 g × mol –1 , hydroxyl number 490–520 mg(KOH) × g –1 , Perstorp Chemicals AB, CAS No. : 326794-48-3) with maleic anhydride (99%, Alfa Asear) in 1,4-dioxane by the procedure. − The compositions of the BH20- COOH were confirmed by Fourier transform infrared (FT-IR) and 1 H and 13 CH nuclear magnetic resonance (NMR) spectroscopy. Proof of the structure and spectral parameters are presented in the Supporting Information (Figures S1–S3).…”

The study of self-assembly processes in polymer solutions is the basis of a modern strategy for creating targeting systems for various substrates. In turn, the use of binary polymer/surfactant systems makes it possible to expand the range of polymers for creating drug delivery systems. This article describes the processes of formation of hybrid micelles based on carboxylterminal hyperbranched polyester polyol Boltorn H20[BH20-COOH] and surfactant Triton X-100[BH20-COOH/TX-100]. Using pH-metry, conductometry, dynamic light scattering (DLS), nanoparticle tracking analysis (NTA), and scanning electron microscopy (SEM), it was shown that at pH = 6.5, a monodisperse [BH20-COOH] associate with a hydrodynamic diameter D h = 79 ± 10 nm and hybrid micelles [BH20-COOH/TX-100] with D h = 114.3 ± 6 nm are formed. Both types of supramolecular associates are able to effectively encapsulate the anticancer drug doxorubicin. The viability analysis of HeLa and MCF-7 cells was performed in the presence of doxorubicin-loaded [BH20-COOH] and hybrid micelles [BH20-COOH/TX-100] in vitro.

“…1,4‐Dioxane was used as a solvent and the ratio of the HBP:MA was 1:6 to 1:18. The materials obtained [maleinized hyperbranched polyester polyol (MHBP)] were used for the synthesis of complexes of Cu, Co, and Ni . In another study, the 1:6 molar ratio of HBP:MA was employed to functionalize a low density polyethylene in the molten state …”

The functionalization of polypropylene (PP) with a maleinized hyperbranched polyester polyol (MHBP) was performed in solution to obtain PP-g-MHBPs. The degree of functionalization (FD) increased with MHBP and dicumyl peroxide (DCP) contents, but the contact angle followed an opposite behavior. The sample obtained with the proportion of 9.0 wt % MHBP and 2.0 wt % DCP and presented the highest FD value. An FD value of 2.4 wt %, produced a reduction of 19 on the contact angle. It was observed by differential scanning calorimetry (DSC) that the PP-g-MHBPs obtained by employing 3.0 wt % of MHBP, exhibited a slight reduction of the melting temperature (T m ) with the increase in the amounts of FD and DCP. Some FD values obtained in this study are higher than those obtained both commercial and noncommercial grades of PP functionalized with maleic anhydride.

“…Moreover, HBPE possesses apparent advantages over linear polymers, for instance, a variety of functional groups, low flexibility, large free-volume, small rheological volume and high solubility in various solvents. [14][15][16][17] Wei et al 18 synthetized the hyperbranched poly (amine-ester) (HPAE) and prepared cross-linked HPAE membrane using glutaraldehyde (GA) as the cross-linker, and discussed its pervaporation properties in separating water/isopropanol mixtures. The cross-linked HPAE membranes presented preferable hydrophilicity and high selectivity towards water.…”

“…Considering the high reactivity and the highly branched three‐dimensional spherical structure of hyperbranched polyester (HBPE), it should be promising to explore the possibility of HBPE as the candidate of membrane material. Moreover, HBPE possesses apparent advantages over linear polymers, for instance, a variety of functional groups, low flexibility, large free‐volume, small rheological volume and high solubility in various solvents .

Water-soluble hyperbranched polyester (WHBP) was synthesized through the esterification reaction of the fourth generation hyperbranched polyester and maleic anhydride. A novel cross-linked WHBP/PVA membrane was prepared by adding WHBP into poly(vinyl alcohol) (PVA) solution with glutaraldehyde as the cross-linker. WHBP was characterized by Nuclear Magnetic Resonance and Attenuated Total Reflection Fourier Transform Infrared Spectroscopy (ATR-FTIR), while WHBP/PVA membranes were characterized by ATR-FTIR, X-ray Diffraction, Scanning Electron Microscopy, Thermogravimetric Analysis, mechanical capacity, and water contact angle. Testing results showed that maleic anhydride was grafted on the surface of WHBP; compared with PVA membrane, WHBP/PVA membrane had lower crystallinity, weaker mechanical strength, higher hydrophilicity, and better thermal stability. Sorption and diffusion behaviors of n-butanol and water in WHBP/PVA membrane were investigated; pervaporation performances of WHBP/PVA membrane were studied through the dehydration of the 90 wt % n-butanol aqueous solution at 40 8C. With an increase of the WHBP content from 0 to 30 wt %, both n-butanol uptake and n-butanol diffusion coefficient first decreased then increased; n-butanol flux first decreased from 10 to 2 gÁm
