Title
Electron phototransfer in the initiating systems for the information registration
Abstract

Electron transfer was shown to be common first stage for photo transformations of different compounds. Free radical formation as a result of electron photo transfer in ferric chloride, chromic acid salts and aromatic carbonyl compounds—benzophenon and its substituted derivatives is discussed. In the presence of vinyl monomers the processes of polymerization initiation, cross-linking and structurization occur. In case of benzophenon and its derivatives the correlations of Hammett's σ-constants with the kinetic characteristics of photo polymerization of vinyl monomers have been found. Investigation of photo polymerization can be an effective tool for studying photo transformations of aromatic carbonyl compounds.
