“…In recent years, biodegradable polymers such as poly(ε‐caprolactone) (PCL), poly(lactic acid) (PLA), polyhydroxyalkanoates (PHAs), and poly(butylene succinate) (PBS) have been extensively investigated due to their attractive biomedical and practical applications . Among them, PLA is the most promising material for the production of environmentally friendly high‐performance plastics.…”

Poly(lactic acid) (PLA) was plasticized with acetyl tributyl citrate (ATBC). The plasticized PLA was further blended with poly(ethylene octene) grafted with glycidyl methacrylate (POE-g-GMA denoted as GPOE) using a twin-screw extruder and the extruded samples were blown using the blown thin film technique. Both ATBC and GPOE significantly influenced the physical properties of the films. Compared to neat PLA, the elongation at break and tear strength of the films were significantly improved. The cavitation and large plastic deformation observed in films subjected to the tear test were the important energy-dissipation process, which led to a torn PLA film. Moreover, the PLA/ATBC/GPOE blown films had better transparency and water tolerance than that of neat PLA. GPOE could act as a tear resistance modifier for PLA blown films. These findings contributed new knowledge to the additives area and gave important implications for designing and manufacturing polymer packaging materials.

“…PBS could be produced from renewable resources, showing of the melting point similar to that of low density polyethylene (LDPE) and tensile strength between PE and polypropylene (PP), as well as excellent processing capabilities 6. However, the crystalline PBS is brittle due to its relatively high crystallinity, and some methods such as adding the additive, inorganic filler, nanocomposite, and other polymers were developed to modify the properties 7–12…”

Poly(butylene succinate)/cellulose diacetate (PBS/CDA) blends were prepared by the solution blending method from poly(butylene succinate) (PBS) and cellulose diacetate (CDA). The influence of hydrogen bond on the structure, morphology, crystallization, as well as the physical properties of PBS/CDA blends was significantly investigated. The fourier transform infrared spectroscopy (FTIR) results indicated that the carbonyl groups of PBS shifted to higher wavenumbers and disappeared at the content of 60% CDA, due to the formation of hydrogen bond between PBS and CDA. The wide-angle X-ray diffractometer (WAXD) and differential scanning calorimeter (DSC) analysis suggest that the crystallization of PBS was significantly restricted by the incorporation of CDA, which is also attributed to the hydrogen bonding. The scanning electron miscroscope (SEM) and polarized optical microscopy (POM) results revealed that PBS and CDA were miscible without appearance of obvious phase separation. The hydrogen bonding interaction led to the change of decomposing mechanism of blends as determined by thermogravimetric analysis (TGA), as well as the increase of the elongation at break due to the reduced crystallinity of PBS. The existence of CDA led to the decrease of water contact angle, showing of the improved hydrophilicity.

“…In recent years, there has been great interest in the development of biodegradable polymers as a key solution to environmental problems 14, 15. These biodegradable polymers are mainly the aliphatic polyesters produced by microbiological and chemical synthesis, natural polymer‐based products, and their blends 16–23. Among them, poly(lactic acid) (PLA), polycaprolactone (PCL), polybutylenesuccinate (PBS), and polybutylensuccinate–butylenecarbonate (PBSC) are commercially available at present.…”

Wood flour (WF)-polycaprolactone (PCL) and polybutylenesuccinate-butylenecarbonate (PBSC) composites were prepared by knead processing. The effects of a compatibilizer on the tensile and thermal flow properties of the composites were investigated. PCL-graft-maleic anhydride (PCL-g-MA) was used as a compatibilizer. Tensile properties were improved by adding PCL-g-MA to both composites. The tensile strength and Young's modulus were increased from 13 to 27 MPa and 581 to 1011 MPa in WF-PCL (50/50, w/w) composites, respectively, and from 17 to 28 MPa and 814 to 1007 Mpa in WF-PBSC (50/50, w/w) composites, respectively, with the addition of 5% PCL-g-MA. Elongation at break increased from 4 to 7% and from 3 to 6% in the WF-PCL and the WF-PBSC composites, respectively. Tensile strength was further increased with increasing WF content in the presence of PCL-g-MA. Thermal flow temperature and melt viscosity of the composites were increased, and water absorption and thickness swelling were improved with the addition of PCL-g-MA. It was found from the burial test that all composites were more than 40% degraded within 6 weeks, and there was no considerable difference in degradation between composites with PCLg-MA and those without.
