The effect of a number of vinyl-containing organosilicon compounds used as the Speier catalyst additives upon the activity of the resulting catalyst was studied. The most active additives turned out to be hexavinyldisiloxane, tetramethyldivinyldisiloxane, and dimethyldivinylsilane. It was found also that the activity of the Speier catalyst additives depends on the method of the catalyst preparation

Quantum-chemical calculation of o-, m-, p-carboranes(12) and C2H2B10Cl10 has been carried out by RHF, DFT(B3LYP) and MP2 methods (6-31G** and 6-311++G**). The analysis of electronic structure of these molecules has been performed. The correlations between electronic and thermodynamic parameters with C-H acidity have been elucidated

Systematic studies on the chemical properties of a new class of compounds – silylchloro derivatives of ethylene and acetylene – and on regularities of their behavior in hydrosilylation, chlorination, and hydroclorination were reviewed. Quite different behavior of the monomers under study in these reactions was found depending on the amount of chlorine atoms and silyl groups and their positions in the molecule, as well as on the nature of substituents at the silicon atom was found.

The preparative gas chromatography method has been used for isolation of heterocyclic organosilicon compounds boiling up to 400o C. The ways are shown for solution of problems which arise in the course of isolation of such high boiling substances.
46-49 192
The thermal stability of organosilicon stationary phases for gas-liquid chromatography has been tested under conditions approximating the real operation of chromatographic column.

The problems of Langasite single crystals growth by Czochralski and Bridgman methods were analyzed. It was found that the deferent kinds of defects in langasite crystals influence on physical properties and thus on langasite crystals application. Vernel method was first proposed for obtaining of qualitative single crystal charge from initial components. A monophase single crystal charge obtaining was confirmed by X-ray diffraction method. A single crystal with uniform composition was obtained by Czochralski method from this charge

Modification of epoxy resins of silicon ethers (tethraetoxysilane – TEOS, and ethylsilicate – ET-40) was investigated. Phase diagrams of mixtures were given by the turbidity points method. It was shown that TEOS and epoxy resins form solutions or emulsions but ET-40 form solutions only. Experimentally found viscosity decreasing with changing of mixtures content was described by mathematical model that accounted rheological behavior of the solutions and emulsions. The rheokinetic studying of the hardening of source and modifying epoxy resins showed that the viscosity rise during the hardening process was connected with the increase of their molecules length and may be calculated by wellknown power equation and was determined by phase structure of mixtures
