Fast and switchable ring-opening polymerization of biorenewable omega-substituted lactones towards sustainable copolymers with facile control over monomer sequences

Abstract

Highly active catalysts for the ring-opening polymerization (ROP) of biorenewable monomers, especially lactones, are essential for sustainable polymers. The (thio)urea/base catalyst systems was found to be active for unsubstituted lactones....
