The basic conditions necessary for realization of single-stage processes of synthesis of polymeric products with optical accuracy are considered in this work. It is shown, that this problem can be solved with a method, which is designated as a method of frontal photopolymerization. The essence of this method will consist in maintenance of process of polymerization as a running wave.For fabrication of products with optical accuracy it is necessary, that polymerization passed actually only in infinitely thin layer on a polymer–monomer boundary.The basic requirements to devices of exposure and to compositions for photopolymerization are considered in this work. It is shown, that only compositions, in which process of radical polymerization passes without breaking, are suitable for these purposes. Such process can be realized at imposing of certain restrictions on molecular movements of reagents, first of all, on their rotary movement.
