Abstract

Abstract : The Cover Feature shows a new approach to cyclic polylactide in the bulk ring‐opening polymerization (ROP) ofl ‐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.
