摘要：

The process of non-catalytic hydrolytic polycondensation of dialkoxydiorganosilanes under elevated pressure has been investigated. It is shown that non-catalytic hydrolytic polycondensation of diethoxydimethylsilane in an autoclave proceeds with complete monomer conversion for 10 min forming predominantly linear oligomers. Complete conversion of diethoxymethylphenylsilane is achieved by stirring or by increasing of the process temperature. In the hydrolytic polycondensation of dialkoxydimethylsilanes in the autoclave without stirring the reactivity of monomer is regularly decreased with increasing of length of the alkoxy-groups in the series of MeO-EtO-(PrO)-O-i-(PrO)-O-n-(BuO)-O-n.
