The method of small-angle scattering of optical radiation has been used to study the dynamics of the concentration inhomogeneities evolution in a photopolymerizable composition based on cross-linking monomer, which is restrictedly compatible with its own polymer. The example of oligocarbonate dimethacrylate OCM-2, shows that after the composition photoinitiation is stopped the inhomogeneities evolve depending essentially on the phase state of the polymerizable medium. In the homophase state, these inhomogeneities relax due to diffusion, and in the heterophase state their amplitude grows due to microphase separation. Basing on this regularity an optical technique is proposed to determine the values of conversion at which the polymerizable medium passes from the homophase state to the heterophase state combining the studies on the kinetics of polymerization by IR spectroscopy. The method to optically control the process of concentration inhomogeneities evolution in the volume of the polymerizing layer by switching the polymerization initiation modes during the homo- and heterophase states of the composition is proposed and experimentally realized.
