ABSTRACT:
This invention provides novel protected, multi-functionalized multi-arm polymers, their optionally hydrogenated analogues and optionally deprotected analogues thereof, and processes for making these compounds. In the invention, monomers are polymerized using a protected functionalized initiator to form living polymer anions, the living anions coupled to form multi-arm polymers, additional monomer added to form additional polymer arms, and the multi-arm polymer functionalized using electrophiles.
