Abstract

This invention provides methods for controlled single electron transfer living radical polymerization (SET-LRP) of monomers with increased conversion, high molecular weights and low polydispersity by allowing the polymerization to proceed at low temperatures via a tubular reactor either made of copper or containing copper metal surface.
