Synthesis of multi-block copolymer stars using a simple iterative Cu(0)-mediated radical polymerization technique

A new iterative copper(0)-mediated radical polymerization approach is presented that represents a significant advance in the synthesis of high order multi-block star copolymers. The synthesis of these materials can now be achieved in high yield and with controlled structural complexity, with purification only required at the last step. The approach is general, facile and offers the opportunity to synthesize new copolymer stars.
