In this communication, we describe a simple and highly efficient route to well-defined multi-block star copolymers based on copper(0)-mediated living radical polymerization. The technique involves a core first approach using a multi-functional initiator in connection with iterative copper(0)-mediated radical polymerization steps. Importantly, purification is not required between the successive chain extension steps as complete monomer conversion is reached before the addition of each consecutive monomer type.
