“…At low monomer conversions, these polymerization systems demonstrate (to various degrees) polymerization slowdown with increasing concentration of the RAFT agent [24][25][26]. In the process, stable intermediates form in concentrations substantially higher than the concentration of growth radicals; intermediates of two types have been experimentally identified as the RAFT agent in the first system with t-BDB.…”

A new mathematical model of Reversible Addition-Fragmentation chain Transfer (RAFT) polymerization is proposed, describing a series of experimental data on styrene bulk polymerization in the presence of various RAFT agents. The polymerization slowdown observed with increasing concentration of the RAFT agent is attributable to the accumulation of intermediate products that participate in chain transfers to both low-molecular and polymer RAFT agents, whereas the length of the initiation period is determined entirely by the activity of the low-molecular RAFT agent.

This paper provides a second update to the review of reversible deactivation radical polymerization achieved with thiocarbonylthio compounds (ZC(=S)SR) by a mechanism of reversible addition-fragmentation chain transfer (RAFT) that was published in June 2005 (Aust. J. Chem. 2005, 58, 379-410). The first update was published in November 2006 (Aust. J. Chem. 2006, 59, 669-692). This review cites over 500 papers that appeared during the period mid-2006 to mid-2009 covering various aspects of RAFT polymerization ranging from reagent synthesis and properties, kinetics and mechanism of polymerization, novel polymer syntheses and a diverse range of applications. Significant developments have occurred, particularly in the areas of novel RAFT agents, techniques for end-group removal and transformation, the production of micro/nanoparticles and modified surfaces, and biopolymer conjugates both for therapeutic and diagnostic applications.

“…Their polydispersity parameters are even lower than when using the low-molecular-weight RAFT agent. Higher performance of polymeric RAFT agents compared to the low-molecular-weight agents was also demonstrated in [9,10]. It is associated with the mechanism of reaction (2), when both fragmentation pathways of intermediate Int 2 are kinetically equivalent and always lead to the formation of the polymeric RAFT agent and to the regeneration of the macroradical.…”

Low-temperature reversible addition-fragmentation chain transfer (RAFT) polymerization of methyl methacrylate

2014

View full text Add to dashboard Cite

Controlled/living radical polymerization of methyl methacrylate under the conditions of reversible addition-fragmentation chain transfer was performed. The reaction occurs at high rates, with the control over molecular-weight characteristics of poly(methyl methacrylate) preserved. The polymeric reversible chain-transfer agent exhibits high performance in polymerization of methyl methacrylate and in its block copolymerization with styrene.
