Abstract: The present invention provides efficient processes for preparing brush polymers. In general, the process comprises three distinct reaction steps utilizing two separate catalysts. In the first step, the initiating compound comprising norbornene is contacted with a silane in the presence of a catalyst, thereby forming a silated intermediate. This silated intermediate is then contacted with a monomer in the presence of a catalyst via Group Transfer Polymerization (GTP). The resulting compound from GTP is contacted with a ring opening metathesis polymerization (ROMP) catalyst to prepare the brush polymer. Surprisingly, the brush polymers obtained from the above process are accessed in an efficient and rapid GTP methodology as compared to prior methods.
