Group transfer polymerization (GTP) is a living polymerization method for acrylic-derived monomers developed by DuPont after living anionic polymerization in the 1980s. The acrylic-derived monomers mainly include acrylate, methacrylate, acrylamide and acrylonitrile. The elementary initiation and propagation reactions in GTP are all rooted in the Mukaiyama-Michael addition reaction. Therefore, in principle both base and acid can sever as the catalyst for GTP. Before the small molecular organocatalyst is applied to the polymerization method, the normally used base has been a soluble ionic compound containing a sterically hindered cation, in which the nucleophilic anion acts as the true catalyst. The normally used acid has been a metal or transition metal compound having Lewis acidity. Since 2007, small organic bases and acids have been gradually used to catalyze GTP, and this type of polymerization has been named as organocatalyzed GTP. Compared with the conventional one, organocatalyzed GTP has made a great improvement in the aspects of molecular weight and molecular weight distribution control of acrylic polymers, scope of polymerizable monomers, topological design of polymer, etc. This review mainly focuses on the author's recent work and will be discussed from four aspects: GTP using organic strong base, GTP using organic strong acid, a novel hydrosilane-based GTP, and polymerization mechanism.
