“…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.

“…The used solvents and precipitating agents were purified according to commonly accepted procedures [10]. BTB and BTC were obtained as described in [11,12] and characterized via 1 H NMR spectroscopy. (Co)polymerization was conducted at 60-80°С in sealed ampoules that were preliminarily degassed in a triple freeze-pump-thaw cycle in vac uum.…”

Controlled radical (co)polymerization of (meth)acrylic esters via the reversible addition-fragmentation chain-transfer mechanism

et al. 2012

View full text Add to dashboard Cite

The homopolymerization of acrylic and fluoroacrylic esters mediated by benzyl dithiobenzoate and dibenzyl trithiocarbonate proceeds in the controlled mode via the reversible addition fragmentation chain transfer mechanism, while the controlled radical polymerization of methacrylic esters is not effected under these conditions. The molecular mass characteristics of the copolymers of acrylic and methacrylic esters may be satisfactorily controlled by benzyl dithiobenzoate-mediated copolymerization when the con tent of acrylic esters is no less than 50 mol %. If a reversible addition fragmentation chain transfer agent active with respect to only one of the monomers is used, compositionally homogeneous narrowly dispersed copolymers are formed via the azeotropic copolymerization of the monomers up to high conversions. The controlled copolymerization of N vinylpyrrolidone and fluoroacrylates allows the synthesis of alternating narrowly dispersed amphiphilic copolymers with properties different from those of alternating copolymers with a broad molecular mass distribution.
