Living free-radical polymerization by reversible addition - Fragmentation chain transfer: The RAFT process
John Chiefari,Y. K. Chong,Frances Ercole,Julia Krstina,Justine Leigh Jeffery,Tam P. T. Le,Roshan T. A. Mayadunne,Gordon Francis Meijs,Catherine Louise Moad,Graeme Moad,Ezio Rizzardo,San H. Thang +11 more
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.
Journal ArticleDOI

Graeme Moad,John Chiefari,Y. K. Chong,Julia Krstina,Roshan T. A. Mayadunne,Almar Postma,Ezio Rizzardo,San H. Thang +7 more
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-

Thiocarbonylthio Compounds (SC(Z)S−R) in Free Radical Polymerization with Reversible Addition-Fragmentation Chain Transfer (RAFT Polymerization). Effect of the Activating Group Z
John Chiefari,Roshan T. A. Mayadunne,Catherine Louise Moad,Graeme Moad,Ezio Rizzardo,Almar Postma,and Melissa A. Skidmore,San H. Thang +7 more
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.
Journal ArticleDOI
Living Radical Polymerization with Reversible Addition−Fragmentation Chain Transfer (RAFT Polymerization) Using Dithiocarbamates as Chain Transfer Agents
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.
Journal ArticleDOI
A novel synthesis of functional dithioesters, dithiocarbamates, xanthates and trithiocarbonates
TL;DR: In this article, a novel synthesis of functional dithioesters, dithiocarbamates, xanthates and trithiocalarbonates is described, which is compatible with a wide range of functionalities (e.g. carboxy, hydroxy and nitrile).
