Free radical photopolymerization dominates most of the industrial applications of photocuring. The most popular are protective coatings, dental fillings, adhesives, inks, lithography (printing plates), stereolithography but also advanced hightechnology purposes (micro and optoelectronics, holographic data storage, etc.) [1]. Currently, radical photopolymerization is also applied to prepare new advanced materials, e.g. nanocomposites, polymer gels, ionogels, polymers with controlled structure, etc. Compared to cationic photopolymerization the free radical initiation is more advanced mainly due to the availability of a wider range of monomers and photoinitiators. Typical chemistry utilized in free radical initiated UV-curable compositions include combinations of monoand multi-functional (meth) acrylate monomers and (meth)acrylated oligomers, which react readily in the presence of radicals. This mini-review describes some representative trends in investigations of the light-induced polymerization.
