Highly active with ultrafast initiation, the catalyst 1 promotes the controlled, living, ring-opening polymerization of various norbornene and 7-oxonorbornene derivatives (see scheme). The high ki/kp ratio associated with the polymerization reactions results in better molecular-weight control and narrower polydispersity indexes (PDIs, ki=rate constant for initiation, kp=rate constant for polymerization).
