Abstract
A new and efficient method of functionalizing high molecular weight polymers through alkylation using a metal hetero alkylbase is described. This novel procedure can also be used to synthesize polymer-based macro-initiators containing radical initiating groups at the chain-ends for synthesis of block copolymers.
