摘要:
Protected, functionalized telechelic polymers, hydrogenated and/or deprotected analogues thereof, and processes to prepare these polymers are disclosed. In the invention, a lithium initiator is added to a compound having at least two independently polymerizable vinyl groups to form a dilithium initiator. Monomer is then added to grow or polymerize polymer arms having living ends and the living ends functionalized.
