Biodegradable poly(lactic acid)/poly(butylene adipate‐co‐terephthalate) (PLA/PBAT) blends and films were prepared by melt blending and blowing films technique in the presence of chain extender. The Joncryl ADR‐4370F (ADR) was used as the chain extender. The effect of ADR on the mechanical properties, rheological behavior, morphology, and thermal behavior of PLA/PBAT blends was investigated. The mechanical properties were markedly improved by incorporation of 0.15 phr ADR, for example, the elongation at break increased from 23.5% to 410.3% and the notched Izod impact strength increased from 7.5 to 33.4 KJ/m2 for the PLA/PBAT/ADR blends. The elongation at break increased from 17.7% to 264.6% and the tensile strength increased from 28.0 to 40.7 MPa for the PLA/PBAT/ADR films in the transverse direction. The tensile strength and tear strength of the films increased from 28.0 to 40.7 MPa and from 135.5 to 163.8 kN/m in the machine direction, respectively. Morphological observation through scanning electron microscopy revealed that the compatibility of the PLA/PBAT blends was greatly enhanced by the incorporation of ADR. The interfacial adhesion was improved between PLA phase and PBAT phase. These findings contributed new knowledge to the additives area and gave important implications for manufacturing biodegradable polymer packaging material. POLYM. ENG.

“…These bioplastics are being used for a variety of different applications, including the automotive, agricultural, pharmaceutical and packaging industries . Biodegradable polymers, such as poly(lactic acid) (PLA) and poly(butylene adipate‐co‐terephthalate) (PBAT), have proven to be effective in solving many of the problems associated with current commercial plastics, including greenhouse gas emissions, and end of life issues . Research on novel combinations of biodegradable polymers with comparatively inexpensive natural fillers, such as commonly found plant biomass, agricultural residues, and industrial co‐products, has expanded greatly over the past few decades …”

This paper investigates the effect of the incorporation of organosolv lignin and a chain extender on the compatibility between polylactide and poly(butylene adipate-co-terephthalate). Bioblends were processed using melt extrusion and injection molding techniques. A reaction was observed during the melt processing as the force increased as the amount of ADR in the formulation increased. This reaction was investigated by Fourier transform infrared spectroscopy. The morphological images showed a good dispersion and an absence of phase separation by the inclusion of the chain extender. The incorporation of the chain extender enhanced the tensile properties and modulus characterization of the bioblends. Dynamic mechanical analysis and rheological characterization revealed that the addition of chain extender increased the storage modulus of the bioblends. Differential scanning calorimetry analysis showed a good miscibility between PLA and PBAT in the presence of OL and the chain extender, while thermogravimetric analysis showed enhancement in the thermal stability by inclusion of the chain extender.

“…These components reacted with HDI and butanediol (BDO) [17][18][19] to obtain a PLA-based thermoplastic elastomer (PLAE). The present study is an alternative approach to the previously reported works on the poly(lactic acid)-blockpolycarbonate diol- [20][21][22] and polylactide-block-poly(butylene adipate) diol- [23][24][25] based thermoplastic elastomers. In this study, the PLA-based thermoplastic elastomer was blended with PLA to improve both thermal and mechanical properties.…”

Polylactide (PLA) was toughened by a PLA-based thermoplastic elastomer (PLAE). PLAE was prepared by chain extension of PLA copolymer derived from polylactic acid (PLA) and poly(tetramethylene ether glycol) (PTMEG) via melt polycondensation. The tensile strength of the toughened-PLA (PLAE30) reached 70 MPa, while the elongation at break was found to be above 140% compared to its plain PLA counterpart. The relationship between the phase morphology of the blends and their mechanical behavior was investigated with atomic force microscopy (AFM), scanning electron microscopy (SEM), and scanning transmission X-ray microscopy (STXM). It was found that the well-dispersed nanoscale structures in the matrix of PLA/PLAE blends are mainly responsible for the significantly enhanced mechanical properties. Also discussed are the detailed microstructural development in PLAE and the toughening mechanism.
