Donnet and Henrich (37) have proposed an aroxylic structure having localized free-radicals on the surface and explained the inhibition in vinyl polymerization
by the so-called quinone radical theory.
Among the topics are the synthesis of hyperbranched polymers via polymerization of functionally symmetric monomer pairs, self-condensing vinyl polymerization
, hyperbranched co-polymers synthesized by co-condensation and radical co-polymerization, hyperbranched and dendritic polyolefins prepared by transition metal catalyzed polymerization, the kinetic theory of hyperbranched polymerization, and biological and medical applications.
With literally thousands of commercial uses, this production method has become a subject of considerable research in both the physical and organic chemistry of radical vinyl polymerization
The former is a vinyl polymerization
and proceeds through carbenium ion formation while the latter is ring opening generating an active species known as an onium ion.
Photoinitiated free radical polymerization of acrylates and methacrylales has enormous commercial importance and has gained much attention because of extensive industrial applications such as curing of coatings on various materials, adhesives, printing inks and photoresizts which are based on photoinitiated radical vinyl polymerization

The self-condensing vinyl polymerization
(SCVP) of p-chloromethyl styrene (CMS) using metal-catalyzed living radical polymerization catalyzed by the complex CuCl/2,2'-bipyridyl has been attempted .
However, diallyl polymerization has not received as much attention in scientific literature as the corresponding vinyl polymerization
, since it is more difficult to polymerize allyl monomers using free radical initiators than vinyl ones (5-7).
Another parameter investigated was the propagation constant, aiming to simulate the kinetics of free-radical vinyl polymerization
systems possessing higher propagation rates.
Inorganic initiators are relatively inexpensive and do not produce undesirable decomposition products compared with the organic initiators commonly employed in free-radical vinyl polymerization
The mechanism of plasma polymerization is much more complex than that of the conventional vinyl polymerization
