Therefore the use of RAFT polymerization in research groups worldwide An electrochemically mediated reversible addition–fragmentation chain-transfer polymerization (eRAFT) of (meth)acrylates was successfully carried out via electroreduction of either benzoyl peroxide (BPO) or 4-bromobenzenediazonium tetrafluoroborate (BrPhN2+) which formed aryl radicals, acting as initiators for RAFT polymerization. Direct electroreduction of chain transfer agents was

    Sigma-Aldrich presents an article about a micro review of reversible addition/fragmentation chain transfer (RAFT) polymerization. RAFT (Reversible Addition/Fragmentation Chain Transfer) polymerization is a reversible deactivation radical polymerization (RDRP) and one of the more versatile methods for providing living characteristics to radical polymerization.

    Reversible Addition-Fragmentation Chain Transfer Polymerization. Reversible addition fragmentation chain-transfer polymerization (RAFT) is a controlled living radical polymerization that is associated with a series of reversible addition-fragmentation steps based on the degenerative chain transfer as a means of converting dormant chains to active propagating radical [120]. reversible addition – fragmentation chain transfer (the life of RAFT) Graeme Moad,* John Chiefari, (Bill) YK Chong, Julia Krstina, Roshan TA Mayadunne, Almar Postma, Ezio Rizzardo and San H Thang CSIRO Molecular Science, Bag 10, Clayton South 3169, Victoria, Australia Abstract: Free radical polymerization with reversible addition

    The fundamentals of controlled radical polymerization are presented in this review. The paper focuses on reversible addition fragmentation chain transfer (RAFT) polymerization. The mechanism and specifics of this type of polymerization are discussed, as are the possibilities of synthesizing complex macro-molecular structures.

    Introduction: Reversible Addition Fragmentation Chain Transfer (RAFT) polymerisation is now an established tool for polymer chemists to create various polymer architectures with precise control over the molecular weight, and to install a variety of different moieties onto the polymer chain ends. Recently, there seems to be a trend of moving polymer science away from the traditional academic Methyl methacrylate was free radically polymerized through the immobilized vinyl bond on the surface in the presence of the reversible additionfragmentation chain-transfer (RAFT) agent 4-cyanopentanoic acid dithiobenzoate using 2,2'-azobisisobutylnitrile (AIBN) as an initiator.
