CAS QIBEBT introduces simple catalyst for polyester synthesis and degradation

The team of WANG Qinggang at CAS Qingdao Institute of Bioenergy and Environental Technology (QIBEBT) has shown Zinc hexamethyldisilazide Zn(HMDS)to be a simple, biocompatible and efficient catalyst for polyesters synthesis and degradation. It capalizes ring-opening polymerization of various lactones to obtain polyesters, such as poly(lactide), poly(3-hydroxybutyrate), and poly(caprolactone),  with controlled molecular weights and narrow molecular weight distributions, but also degradation of polyesters into valuable depolymerization products with excellent yields and chemoselectivity.
