Abstract 

Light induced reactions are based on the absorption of light that
excites the electrons of a molecule and can, under favorable circumstances, lead
to dissociation, isomerization, abstraction, electron or energy transfer, and bond
formation. These reactions have been the subject of many studies in various fields
including organic chemistry, molecular biology, electronics etc. Light induced
reactions can advantageously be utilized in the field of polymer chemistry.
Among them, light induced polymerization is of enormous commercial
importance. Techniques such as curing of coatings on wood, metal and paper,
adhesives, printing inks and photoresists are based on photopolymerization.
There are some other interesting applications, including production of laser
video discs and curing of acrylate dental fillings. In this chapter, general methods
for the light induced polymerization processes involving radical and ionic
reactions are described. Special emphasize is devoted to their application to
more complex macromolecular structures such as block, graft and star copolymers,
and polymer nanocomposites based on clay and metal.
