Although photopolymerization is a rather old and well established tool, numerous new applications are addled year bu year. Therefore, the development of new tailor made components for radical and cationic systems is still in progress.

In Car Refinnish bodyshops daylight bulbs/UV-A lamps are preferred for obvious safety reasons. These light sources do not expose dangerous irrediation. Recently, a robust daylight curing clearcoat based on isocyanate/thiol chemistry had been launched on the market.

The Synthesis and photochemical reaction of certain novel dentritic polymers containing methacryloyl groups were examined.

Several arene-iron complexes were tested as photoinitiators for cationic polymerization. The UV light decomposes arene-iconcyclopentadienyl cation selectively to the corresponding aromatic compound and iron cyclopentadiene cation.

Organoclay were prepared by cationic exchange process between  Na+ions of montmorillonite in bentonite clay and two types of alkyl amines

The improved or unusual features of organic-inorgannic hybrid materials are today well established. They allow the development of innovative industrial applications in mary areas: optics, electronics, biology, medicine...

Radiation curing is a well established technology that has enabled a wide variety of applications in coatings, graphic arts and electronic materials. Most applications rely on radically curable formulation, since this process allows a very fast transformation of a liquid high-solid formulation into a cured material at ambient temperature.

Schuster an co-workers discovered that 1.4-disyanonaphthalene solutions containing an alkyltriphenylborate salt, when irradiated, yield one electron oxidation of the alkyltriphenylborate leading to carbon-boron bond clravage and formation of free alkyl radicals.
