Heterofunctional condensation of chlorosilanes with tetra- and hexaphenylsiloxanediols
A number of new chloro- and hydrochlorosiloxanes with cyclic and linear structures were synthesized by the condensation of tetraphenyldisiloxane-1,3-diol and hexaphenyltrisiloxane-1,5-diol with silicon tetrachloride and trichlorosilane. The effects of the starting ratio of the reactants and dilution on the reaction rates and yields of cyclosiloxanes were studied.
