原子转移自由基聚合 Atom Transfer Radical Polymerization, ATRP ATRP or Atom Transfer Radical Polymerization is a Polymerization reaction involving free radicals. It was introduced as an extension to ATRA or Atom Transfer Radical Addition by Jinshan Wang and Matyjaszewski, (1995) and Sawamoto (1994/5).

Dr. Graeme Moad CSIRO Molecular and Health Technologies, Bayview Avenue, Clayton, Victoria 3168, Australia He joined CSIRO as a research scientist in 1979 and is currently a chief research scientist. Dr Moad is coauthor of the book ‘The Chemistry of Free Radical Polymerization’ which appeared as a second edition in 2006. His research interests lie in the fields of polymer design and synthesis (free radical polymerization, reactive extrusion), polymerization kinetics and mechanism, and most recently polymer nanocomposites.
Dr. Ezio Rizzardo CSIRO Molecular and Health Technologies, Bayview Avenue, Clayton, Victoria 3168, Australia Ezio Rizzardo is a graduate of the University of New South Wales and received his Ph.D. from the University of Sydney for his studies on the photochemistry of nitro compounds. He joined CSIRO in 1976 after a postdoc at Rice University, RIMAC, and the Australian National University. His CSIRO research has focused on developing methods for controlling free radical polymerization. For this he has received a number of awards including the RACI Australian Polymer Medal and the CSIRO Chairman’s Gold Medal. Currently he is a CSIRO Fellow and a Fellow of the Australian Academy of Science.
Dr.San H. Thang CSIRO Molecular and Health Technologies, Bayview Avenue, Clayton, Victoria 3168, Australia San H. Thang was born in Saigon, Vietnam, in 1954 and came to Australia in 1979 as a refugee. He completed his B.Sc.(Hons) degree in 1983 and Ph.D. in 1987 from Griffith University. He joined CSIRO in 1986 as a research fellow. He then moved to ICI Australia in late 1987 to undertake the challenge of industrial research. He returned to CSIRO in late 1990, and in 1995 he was co-inventor of the RAFT Process. He is currently a senior principal research scientist at CSIRO Molecular and Health Technologies where his research focuses on the interface between organic and polymer chemistry.
