TL;DR: The authors proposed a reversible additive-fragmentation chain transfer (RAFT) method for living free-radical polymerization, which can be used with a wide range of monomers and reaction conditions and in each case it provides controlled molecular weight polymers with very narrow polydispersities.

TL;DR: In this article, free radical polymerization with reversible addition-fragmentation chain transfer (RAFT polymerization) is discussed with a view to answering the following questions: (a) How living is RAFT polymerization? (b) What controls the activity of thiocarbonylthio compounds in RAFT polymers, and (c) How do rates of polymerization differ from those of conventional radical polymerisation? (d) Can RAFT agents be used in emulsion polymerization; and (e) Retardation, observed when high concentra-

TL;DR: In this paper, two series of chain transfer agents (SC(Z)S−CH2Ph and SC(ZS−C(Me)2CN) were used for styrene polymerization.

TL;DR: In this article, the nonbonded electron pair of the nitrogen included as part of an aromatic system was used as an additive component for living radical polymerization with reversible addition−fragmentation chain transfer.

TL;DR: In this paper, it is shown that a small number of dead chains are produced by radical-radicaltermination of a trithio-carbonate moiety, and that the active functionality should be located in the center of the chain.
