This workshop will focus on recent progress in the rapidly developing field of reversible deactivation radical polymerization. With the great success of the long-standing ACS POLY symposium on the topic, and organized by Kris Matyjaszewski, Nicolay Tsarevsky, Haifeng Gao, and Brent Sumerlin, these organizers are planning a workshop that will bring together leaders in the field on the latest advances.
