Abstract

Controlled radical polymerization has been introduced by IUPAC as one of the research
areas which has grown rapidly in the last decade. Currently, this method has become
the main tool of polymer chemists and it has opened a new way towards very exciting
fields of macromolecular engineering and nano-technology. Among the various techniques
of controlled radical polymerizations, the generative transfer with alkyl iodides is one of
the oldest methods. This method, known as the "iodine transfer radical polymerization",
was used first time in the preparation of fluorinated elastomers. Recently, reverse iodine
transfer radical polymerization has been introduced as a new method without the need
for alkyl iodides. Reverse iodine transfer radical polymerization has emerged as an easy,
efficient and robust method of control radical polymerization, applicable to a wide range
of monomers and compatible with both homogeneous and heterogeneous processes. In this
study, the mechanism and kinetics of (reverse) iodine transfer radical polymerization has
been studied. In addition, the commercial monomers, polymerized by these methods, and
the transfer agents used in these procedures have been reviewed.
