The polymerization of most monomers that are polymerizable by radical polymerization can be controlled by the reversible addition-fragmentation chain transfer (RAFT) process. However, it is usually required that the RAFT agent be selected according to the types of monomer being

Articles

A series of polymerization were carried out using RAFT agents and monomers yielding well-defined polymers with narrow molecular weight distributions. The process allows radical-initiated growing polymer chains to degeneratively transfer reactivity from one to another through the use of key functional groups (dithioesters, trithiocarbonates, xanthates and dithiocarbamates). RAFT agents help to minimize out-of-control growth and prevent unwanted termination events from occurring, effectively controlling polymer properties like molecular weight and polydispersity. RAFT agents are commercially available. RAFT does not use any cytotoxic heavy metal components (unlike ATRP).

The modification of biomacromolecules, such as peptides and proteins, through the attachment of synthetic polymers has led to a new family of highly advanced biomaterials with enhanced properties.

We 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.

Sigma-Aldrich presents an article about RAFT, or Reversible Addition/Fragmentation Chain Transfer, which is a form of living radical polymerization.

We presents an article featuring procedures that describe polymerization of methyl methacrylate and vinyl acetate homopolymers and a block copolymer as performed by researchers at CSIRO.

Sigma-Aldrich presents an article about the typical procedures for polymerizing via ATRP, which demonstrates that in the following two procedures describe two ATRP polymerization reactions as performed by Prof. Dave Hadddleton′s research group at the University of Warwick.
