Abstract
Silicate glass and cotton fabric are hydrophobized via treatment of their surface by vinyltriethoxysilane and oligovinylsiloxane. The data of electron microscopy for chemical analysis and the values of contact angles suggest that the hydrophobicity of the surface layer develops via the polymerization of vinyl groups. The arrangement of vinyl groups in neighboring units in oligovinylsiloxane is favorable for formation of a more uniform solid coating with enhanced hydrophobicity. The use of oligovinylsiloxane and its derivatives with amino and carboxyl groups as surfactants in the heterophase polymerization of styrene makes it possible to obtain stable suspensions with a narrow particle size distribution.
