Norbornene‐ended polybutadiene (PBu) macromonomers have been prepared via two different routes: α‐norbornenyl‐polybutadiene was derived from a norbornene‐containing carbanionic initiator, whereas ω‐norbornenyl samples were obtained through deactivation of living polybutadienyl anions by a norbornene‐based deactivator. Out of four alkylidene complexes tried, the molybdenum alkylidene complex that contains two alkoxide ligands was found to be the most suitable initiator for the ring‐opening metathesis polymerization of these macromonomers.
