Living Radical Polymerization with Nitrogen Catalyst: Reversible Chain Transfer Catalyzed Polymerization with N-Iodosuccinimide

Macromolecular Architectures Designed by Living Radical Polymerization with Organic Catalysts

“…RTCP and RCMP can be facile and pervasive methodologies for various applications. We previously reported the use of RTCP and RCMP in preparing well-defined linear polymers including homopolymers, random copolymers, and diblock copolymers [16][17][18][19][20][21][22][23][24][25][26][27]. In this paper, we report new examples of diblock copolymers and summarize the diblock copolymers prepared in previous and current works.…”

“…This I 2 /azo method was originally invented by Lacroix-Desmazes et al for iodide-mediated LRP [29,30]. This method was also effective for RTCP [17,18] and RCMP [25,27]. A low-polydispersity diblock copolymer (PDI = 1.39) was obtained (entry 3).…”

“…We developed two mechanistically different systems referred to as reversible chain transfer catalyzed polymerization (RTCP) [16][17][18][19][20][21][22][23] and reversible coordination mediated polymerization (RCMP) [24][25][26][27].…”

“…RTCP consists of a dormant species, a catalyst (deactivator), and a radical source that supplies Polymer•. The catalysts include germanium, phosphorus, nitrogen, oxygen, and carbon-centered iodides including N-iodosuccinimide (NIS) (Figure 1) [17] used in the present work.…”

Living Radical Polymerization via Organic Superbase Catalysis

“…We recently developed new LRP systems using iodine as a capping agent and organic molecules as catalysts. We developed two mechanistically different systems, referred to as reversible chain transfer-catalyzed polymerization (RTCP) [25][26][27][28][29][30][31] and reversible coordination-mediated polymerization (RCMP) [31][32][33][34][35]. These polymerizations are metal-free systems.…”
