In this paper, the results of the synthesis of vinyl ethynyltriethoxysilane monomer are simulated on the basis of available industrial products of
tetraethoxysilane and vinyl ethynyl magnesium bromide. The main physical properties of IR and UV spectroscopy have been determined, and a synthesis procedure has been developed that makes it possible to obtain compounds with high yields without laborious additional operations. The new substances obtained were identified by IR and UV spectroscopic methods and their melting point, refractive index, density, and other physical and chemical parameters were determined. The effect of the initial ratio of the components and the nature of the solvents on the yield of the polymer at different temperatures and the duration of the reaction was studied. The influence of the nature of organic solvents on the yield of this reaction product was studied. It is determined that the reaction rate increases with increasing polarity of the solvent .
Keywords: Monomer, tetraethoxysilane, vinyl ethynyl magnesium bromide, vinyl ethynyltriethoxysilane, polyvinylethynyltriethoxysilane, IR, UV-spectroscopy, boiling point, refractive index, density, specific viscosity.
