WebOct 27, 2024 · Abstract Blending with biodegradable poly (butylene succinate) (PBS) is an effective way for improving the performance of PLA reactive extrusion. Multifunctional monomer trimethylolpropane tri-acrylate (TMPTA) is used as chain extender to react with PLA and PBS to generate graft copolymers at the PLA/PBS interface. WebApr 1, 2024 · Abstract. Poly (lactic acid) or poly (lactide) (PLA) is a renewable, bio-based, and biodegradable aliphatic thermoplastic polyester that is considered a promising alternative to petrochemical-derived polymers in a wide range of commodity and engineering applications. However, PLA is inherently brittle, with less than 10% elongation at break …
