Abstract:	This paper presents the results of laboratory modeling of polymerization under the action of free-space factors. The relationships between temperature and stoichiometric ratios were obtained for different sublimation parameters of the reaction mixture components and rates of matrix polymerization. It was shown that there exists an optimal relation between the rates of polymerization and sublimation of low-molecular mixture components. The possibility of using low-molecular components with high sublimation rates under certain conditions of reaction development was experimentally verified.Two options for triggering the reaction have been tested—raising the temperature to the value at which polymerization begins and by means of sunlight photoinitiation (ultraviolet spectrum). It was shown that both variants can be used in the conditions of free space.
