报告内容简介:

The Atom Transfer Radical Polymerization (ATRP) process developed at
Carnegie Mellon by Professor Krzysztof Matyjaszewski in 1994 is among
the most effective and most widely used methods of conducting a
controlled radical polymerization (CRP). The Matyjaszewski Polymer Group
continues to improve ATRP and prepare materials with controlled topology
and composition suited for many applications, including automotive,
building materials, medical, military and environmental fields using
this robust technology.

Relying solely on mild ultraviolet irradiation of thiocarbonylthio
compounds in the presence of vinyl monomers, a new avenue to
well-defined ultrahigh molecular weight (UHMW) polymers has been
developed. Through the use of aqueous conditions, well-controlled
polymers with high molecular weights that are unprecedented for
controlled radical polymerizations have been achieved. This
photomediated polymerization approach reaches number-average molecular
weights in excess of 8.00  106 g/mol with degrees of polymerization
above 85,000, making these, to our knowledge, the highest molecular
weight polymers ever achieved via reversible-deactivation radical
polymerization. In many cases, well-defined UHMW polymers can be
obtained in minutes. The utility of the technique is further
demonstrated through the synthesis of block copolymers, enabling access
to a new field of well-defined UHMW materials and polymers that can
undergo dramatic transformations in their topology via a process we call
macromolecular metamorphosis.

Kris Matyjaszewski is J.C. Warner University Professor of Natural
Sciences at Carnegie Mellon University. He discovered Cu-mediated atom
transfer radical polymerization, commercialized in 2004 in US, Japan and
Europe. He has co-authored >1000 publications (cited >126,000
times, h-index 171, Google Scholar) and holds 59 US patents.
Matyjaszewski received 2017 Franklin Medal in Chemistry, 2015 Dreyfus
Prize in Chemical Sciences, 2014 National Institute of Materials Science
(Japan) Award, 2011 Wolf Prize in Chemistry, 2009 Presidential Green
Chemistry Challenge Award, and from the ACS: 2015 Overberger Prize, 2013
AkzoNobel North America Science Award, 2011 Hermann Mark Award, 2011
Award in Applied Polymer Science, 2002 Polymer Chemistry Award, 1995
Creative Polymer Chemistry Award. He received 10 honorary degrees and is
a member of National Academy of Engineering, Polish Academy of Sciences,
Russian Academy of Sciences, and National Academy of Inventors.

Brent Sumerlin graduated with a B.S. from North Carolina State
University in 1998 and received his Ph.D. in 2003 at the University of
Southern Mississippi under the direction of Dr. Charles McCormick. He
continued his work as a Visiting Assistant Professor/Postdoctoral
Research Associate in the group of Krzysztof Matyjaszewski at Carnegie
Mellon University from 2003–2005. In 2005 he joined the Department of
Chemistry at Southern Methodist University as an Assistant Professor,
and in 2009 he was promoted to Associate Professor with tenure. In the
fall of 2012, Prof. Sumerlin joined the Butler Polymer Research
Laboratory and the Center for Macromolecular Science & Engineering
within the Department of Chemistry at the University of Florida, where
he is currently the George Bergen Butler Professor of Polymer Chemistry.
He is a Fellow of the Royal Society of Chemistry and was been named a
Kavli Fellow (Frontiers of Science, National Academies of Sciences).
Prof. Sumerlin has won a number of awards, including the Alfred P. Sloan
Research Fellow, NSF CAREER Award, ACS Leadership Development Award,
Journal of Polymer Science Innovation Award,
Biomacromolecules/Macromolecules Young Investigator Award, and the
Hanwha-Total IUPAC Award. He is an associate editor of ACS Macro
Letters.
