Mechanism of Dithiobenzoate-Mediated RAFT Polymerization: A Missing Reaction Step
Macromol. Rapid Commun. 2006, 27, 1299-1305.
 

The debate on the mechanism of dithiobenzoate-mediated RAFT polymerization may be resolved by including the reaction between a propagating radical and the star-shaped combination product from irreversible termination into the kinetic scheme. By this step, a highly reactive propagating radical and a not overly stable three-arm star species are transformed into the resonance-stabilized RAFT intermediate radical and a very stable polymer molecule. The time evolution of concentrations is discussed for the main-equilibrium range of CDB-mediated methyl acrylate polymerization.
