Ring-Opening Polymerization of l-Lactide to Cyclic Poly(Lactide) by Zeolitic Imidazole Framework ZIF-8 Catalyst

Ring-Opening Polymerization of l-Lactide to Cyclic Poly(Lactide) by Zeolitic Imidazole Framework ZIF-8 Catalyst
Kui Zhou, Somboon Chaemchuen, Francis Verpoort, Zhixiong Luo
The Cover Feature shows a new approach to cyclic polylactide in the bulk ring-opening polymerization (ROP) of l-lactide by using ZIF-8 as a heterogeneous catalyst. The ZIF-8 catalyst assembled by spray-drying technique displays high efficiency and good recyclability for this ROP reaction. The active acid and basic sites in ZIF-8 are supposed to cooperatively catalyze the ROP reaction, particularly forming cyclic polylactide with high molecular weight. More information can be found in the Communication by Luo et al.
