Carnegie Mellon University chemists create versatile polymer brushes

ing chain end with a special catalyst, including hybrid catalysts with low levels of metals in solution. As Matyjaszewski explains, monomers are added to the chain end one unit at time. The process can also be shut down or re-started at will, depending on how the temperature and other conditions are varied. This methodology allows precise control over the composition and architecture of the many structures they can create.

Matyjaszewski's groundbreaking paper on ATRP, first published in 1995, has spawned considerable industrial and academic research in this field of controlled polymerization and has been cited more than 700 times. He heads a research consortium that interacts with 21 industrial companies from around the world interested in creating novel polymeric materials for their markets. Some corporations have licensed ATRP technology and started commercial production. The present consortium, built on the first ATRP consortium founded in 1995 with 11 international industrial organizations, aims to explore the polymer science underlying their targeted activities, and to train both university and industrial scientists in procedures for responsive polymeric material development. The Center for Macromolecular Engineering (www.chem.cmu.edu/groups/maty/) is funded both by the consortium and government agencies, including the National Science Foundation and the Environmental Protection Agency.

Dr. Matyjaszewski carries out research on molecular brushes in collaboration with Professor Martin Moeller, University of Aachen; Professor Tadeusz Pakula, Max Planck Institute, Mainz; Professor Sergei Sheiko, University of North Carolina, Chapel Hill; and Professor Tomasz Kowalewski, Carnegie Mellon.
