The polyamide-6 based poly(ether-block-amide) (PEBA) multiblock copolymers were reactively prepared in typical processing equipment, torque rheometer. The reactive processing conditions of PEBA were discussed in details on the base of the tensile strength as the main quantization parameter and the torque rheological curves.The optimized reaction temperature, reaction time, and rotational speed were 150°C, 10 min, and 40 rpm respectively. The chemical structure, tensile properties, thermal transition, thermal stability, water absorption, and solubility in organic solvents of PEBA prepared in optimized reaction conditions were characterized by Fourier transform infrared spectroscopy, tensile testing, differential scanning calorimetry, thermogravimetric analysis, and soaking testing in water and organic solvents. The tensile strength and elongation at break of PEBA are 35.9 MPa and 580% respectively. The glass transition temperature and melting temperature of soft segment of PEBA are −50 and 15°C, respectively; the glass transition temperature and melting temperature of hard segment of PEBA are 50 and 140°C respectively. Meanwhile, the PEBA has low water absorption, robust organic solvent resistance, and good thermal stability. The optimization process of PEBA will give the deep understanding of reactive processing of polymer materials.

Corn starch was crosslinked with epichlorohydrin (ECH) and then plasticized with glycerol. Subsequently, this thermoplasticized crosslinked starch (TPCLS) was melt‐compounded with polylactide (PLA) and poly(ether‐block‐amide) (PEBA) to prepare biodegradable PLA/PEBA/TPCLS blend with high impact resistance. It was found that the crosslinking agent ECH had critical effect on the impact strength, tensile properties, and internal morphology of the ternary blend. The impact strength, tensile strength, and elongation at break increased with ECH content; thereafter, they decreased on further increasing the ECH content. At 0.5 wt % ECH content, impact strength, tensile strength, and elongation at break reached the maximum values and smaller salami structure particles were observed accordingly. These results were attributed to the competition of shear resistance of TPCLS and the chemical linkage between the crosslinked starch and PLA‐g‐MA. © 2015 Wiley Periodicals, Inc. J. Appl. Polym.

“…The use of petroleum‐based plastics for products and packaging has become ubiquitous in industry, a trend that is contributing heavily to ecological problems such as increased CO 2 levels, pollution of land and waterways, and overloading of the solid‐waste stream. Although petroleum plastics are extremely versatile and fulfill the performance requirements for a multitude of applications, increasing public awareness of their environmental impacts has spurred efforts to replace petroleum feedstocks with sustainable and ecofriendly alternatives . Motivated by the goal to reduce our carbon footprint and dependence on fossil carbon sources, bio‐based polymers and composites are becoming widely utilized in polymer manufacturing and medical applications .…”

One of the most significant limitations to widespread industrial implementation of emerging bioplastics such as poly(lactic acid) and poly(hydroxyalkanoate) (PHA) is that they do not match the flexibility and impact resistance of petroleum-based plastics like poly(propylene) or high-density poly(ethylene). The basic goal of this research is to identify alternative, affordable, sustainable, biodegradable materials that can replace petroleum-based polymers in a wide range of industrial applications, with an emphasis on providing a solution for increasing the flexibility of PHA to a level that makes it a superior material for bioplastic nursery-crop containers. A series of bio-based PHA/poly(amide) (PA) blends with different concentrations were mechanically melt processed using a twin-screw extruder and evaluated for physical characteristics. The effects of blending on viscoelastic properties were investigated using small-amplitude oscillatory shear flow experiments to model the physical character as a function of blend composition and angular frequency. The mechanical, thermal, and morphological properties of the blends were investigated using dynamic mechanical analysis, differential scanning calorimetry, thermogravimetric analysis, scanning electron microscopy, and tensile tests. The complex viscosity of the blends increased significantly with increasing concentration of PHA and reached a maximum value for 80 wt % PHA blend. In addition, the tensile strength of the blends increased markedly as the content of PHA increased. For blends containing PA at >50 wt %, samples failed only after a very large elongation (up to 465%) without significant decrease in tensile strength. The particle size significantly increased and the blends became more brittle with increasing concentration of PHA. In addition, the concentration of the PA had a substantial effect on the glass relaxation temperature of the resulting blends. Our results demonstrate that the thermomechanical and rheological properties of PHA/PA blends can be tailored for specific applications, and that blends of PHA/PA can fulfill the mechanical properties required for flexible, impact-resistant bio-based nursery-crop containers.
