TLDR
Group-transfer polymerization (GTP) as discussed by the authors is a very useful synthetic method for the preparation of acrylic ester polymers and can be used to prepare a wide variety of complex polymer structures.Abstract:
Group-transfer polymerization is a very useful synthetic method for the preparation of acrylic ester polymers. This living polymerization process works well at room temperature and can be used to prepare a wide variety of complex polymer structures. Mechanistic work suggests that GTP is a form of anionic polymerization where propagation occurs via a small concentration of enolate anions which are in equilibrium with dormant silyl ketene acetal chain ends. GTP will find the most use in specialty applications including dispersants, toners, photoresists, and rheology control agents.read more

Expanding the Scope of Group Transfer Polymerization Using N-Heterocyclic Carbenes as Catalysts: Application to Miscellaneous (Meth)acrylic Monomers and Kinetic Investigations
TL;DR: In this paper, N-heterocyclic carbenes were shown to catalyze the solution group transfer polymerization (GTP) of miscellaneous monomers in a controlled fashion at room temperature, in the presence of 1-methoxy-2-methyl-1-trimethylsiloxypropene (MTS) as initiator.
