The compounds 1,4‐butanediol, succinic anhydride, and nanocellulose (NCC) were used to synthesize poly(butylene succinate)‐grafted Nanocrystalline Cellulose (PBS‐g‐NCC) nanocomposites via polymerization in situ. The resulting structures were examined by transmission electron microscopic (TEM), scanning electron microscope (SEM), 1H and 13C‐nuclear magnetic resonance spectroscopic (NMR), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and X‐ray diffraction (XRD) analyses. TEM showed the cellulose to be nanoscale and SEM analysis indicated that 3 wt% NCC dispersed well in PBS matrix. 1H and 13C‐NMR analyses indicated the product to possess peaks characteristic of PBS. DSC analysis clearly showed that the NCC increased the PBS crystallinity when 3 wt% NCC was introduced into PBS matrixes by polymerization in situ, compared to pure PBS. TGA illustrated that the thermal stability of PBS‐g‐NCC was better than that of pure PBS, when 3 wt% NCC was added. XRD analysis suggested that 3 wt% NCC improved PBS crystallinity, which was in good agreement with the present DSC results. POLYM. ENG. SCI., 59:928–934, 2019. © 2018 Society of Plastics Engineers

“…This fact has been used by other authors to conclude that the copolymer has been obtained by the polycondensation of PEG, SA, and BD . There is no signal at 1100 cm −1 in the spectrum of unmodified PBS . Intensities of COC absorption peaks from ester bond (1200–1300 cm −1 ) were weaker than that of ether (1200–1300 cm −1 ) with PEG MW increase.…”

Researching for new biomaterials intended for drug delivery systems has considerably intensified in recent years. There is an increasing interest in PBS (poly[butylene succinate]) and its copolymers as biomaterials due to the possibility of synthesis of the PBS from a renewable source. Among these copolymers, PBS‐PEG (poly[butylene succinate‐co‐polyethylene glycol]) is studied for materials that have shape memory and are biodegradable. However, to date, no research into the use of PBS‐PEG to prepare microspheres for drugs release has been reported. Herein, PBS‐PEGs with three PEG with different chain′s length were synthesized by polycondensation reaction and characterized by means of SEC, FTIR, DSC, TGA, and DRX. Naproxen loaded microspheres were prepared by an oil‐in‐water (o/w) single emulsion technique. The drug release was followed by UV‐Vis. The presence of PEG had a marked effect on the in vitro release profiles. The mathematical models employed show that the fundamental mechanism of release is diffusion when PEG is present in the polymer matrix of the particle.

“…PBS was prepares as described by our group elsewhere. [12][13][14][16][17][18]24] Equimolar amounts of 1,4butanediol (27 mL) and succinic acid (35.9 g) were used. The system was mounted using a heating plate under vacuum and nitrogen flow.…”

“…[9,10] Among the biodegradable polymers, poly (butylene succinate), PBS, can be obtained from petrochemical sources or by a wholly renewable route from chemical intermediates produced in the carbohydrates fermentation such as sucrose, glucose, maltose, and fructose. [11] PBS has excellent processability, biodegradability, low production value [12][13][14][15][16][17][18] and its microbiological degradation generates final products such as CO 2 and H 2 O. [19][20][21] Although PBS has good properties for application as a coating material in controlled release systems, its highly linear structure implies low melt strength, low viscosity, and low barrier property that limit some final applications of this biopolymer.…”

The risks of environmental damage are inherent in oil activities, being a constant concern to our modern society. Among the remediation strategies, the biological one is safer and more inexpensive compared to physic‐chemicals approaches. Bioremediation can be enhanced using biodegradable polymers as coating materials of the nutrient release systems. However, some of these polymers can be improved using electromagnetic radiation, able to modify their properties, such as, molar mass, changing the materials physicochemical behavior. Thus, immobilizing urea in poly (butylene succinate) (PBS) matrix, producing a petroleum bioremediation tool was the primary goal in the paper herein. The composites were obtained by melting at 110 °C with subsequent application of gamma (γ) radiation at doses of 15, 25, 50, and 75 kGy. The obtained results allowed to infer that the increase of the γ radiation doses improved the immobilization, thus reducing the immediate urea release. Besides that, the preliminary biodegradation results showed that the highest rates of hydrocarbon reduction at the end of the analysis period were reached using the material irradiated at 25 kGy. These results are encouraging and proved that irradiated PBS‐urea systems could be used as oil spill disasters tool.
