A simple and efficient route to well-defined multi-block star copolymers has been developed by scientists at the University of New South Wales, Australia.
Based on copper(0)-mediated living radical polymerization, the method involves a core first approach using a multi-functional initiator in connection with iterative copper(0)-mediated radical polymerization steps. No purification is required between the successive chain extension steps as complete monomer conversion is reached before the addition of each consecutive monomer type.
