Abstract
A method for producing a macrocyclic polymer comprising: (a) polymerizing a monomer using a dibrominated initiator having either an aromatic or ester moiety via atom transfer radical polymerization (ATRP) to form a polymer precursor having brominated, phenylated end groups; and (b) cyclizing the polymer precursor using intramolecular atom transfer radical coupling (ATRC) to form the macrocyclic polymer.
