Using atom transfer radical polymerization in environmentally benign processes

Atom Transfer Radical Polymerization (ATRP) is a controlled/"living" radical polymerization system that allows for the synthesis of well-defined polymers with predetermined molecular weights, functionalities, and architectures. The ability to control these parameters enables the preparation of polymeric materials with novel, and heretofore unknown, utility. Materials prepared by ATRP perform more efficiently than comparable polymers, require less material to manufacture, and generate less catalytic waste than conventional processes. This paper describes the latest progress in the development of more efficient catalyst systems for ATRP, the extension to more environmentally friendly media, and some of the advanced materials prepared.
