On the expedition to replace the toxic tin catalyst for PLA production with a benign one, the high potential of germanium complexes as catalysts for industrial relevant conditions were discovered. The catalysts presented polymerize lactide in bulk at 150 °C with high efficiencies and with reaction rates of up to two magnitudes higher than the industrially used tin compound while producing long chain...
Polylactide (PLA) is a high potential bioplastic that can replace oil‐based plastics in a number of applications. To date, in spite of its known toxicity, a tin catalyst is used on industrial scale which should be replaced by a benign catalyst in the long run. Germanium is known to be unharmful while having similar properties as tin. Only few germylene catalysts are known so far and none has shown...
