摘要
Abstract
This review systematically summarized the catalytic systems used in the melt polycondensation of poly(lactic acid)(PLA).It covers conventional metal-based catalysts(e.g.,tin and titanium compounds)and low-toxicity alterna-tives(e.g.,rare-earth compounds and phosphotungstic heteropolyacids),with special emphasis on their catalytic mecha-nisms and influence on final product properties.The development of binary and multi-component composite catalysts was highlighted,as these systems demonstrate remarkable synergistic effects that enhance catalytic activity,reaction rate,and the optical purity and thermal stability of PLA.Particular attention was given to the coordination between composite catalysts and stepwise catalytic processes,offering theoretical and technical pathways for the green and controllable syn-thesis of high-performance PLA.Future research should focus on developing efficient,low-toxicity catalysts,optimizing synergistic combinations,refining processing technologies,and elucidating polymerization kinetics to facilitate the pro-duction of high-molecular-weight PLA.These advancements are crucial for expanding the industrial application of PLA as a competitive biodegradable material within circular economy systems.关键词
