Abstract

The article describes the results of a research on polycondensation «in situ» in the processes of partial hydrolysis of C2H5O(CH3)2SiOSi(CH3)2OC2H5. The influence of the molar ratio of reagents on the oligomeric composition of the partial hydrolysis products and the dependence of the monomer conversion degree on conversion of functional groups are presented. A comparison of the patterns of macromolecules formation in the processes of partial hydrolysis of 1,1,3,3-tetramethyl-1,3-diethoxydisiloxane and homofunctional condensation of 1,1,3,3-tetramethyldisiloxane-1,3-diol is carried out.
