Synthesis of a Conjugated Macromolecular Initiator for Nitroxide-Mediated Free Radical Polymerization

Abstract

Controlled synthesis of rod-coil block copolymers is possible with a new macroinitiator for "living" nitroxide-mediated radical polymerization (NMRP). The synthesis of the new macroinitiator which contains a rodlike, conjugated poly(p-phenylene vinylene) block is described. Electron microscopy imaging indicates microphase separation of the resulting block copolymer when cast from chloroform.
