By means of a reaction of heterofunctional condensation we obtained 1,7-divinyl-1,7-dimethyloctaphenylcyclohexasiloxane. The reaction of hydrid polyaddition of αω-dihydriddimethylsiloxanes to 1,7-divinyl-1,7-dimethyloctaphenylcyclohexasiloxane in the presence of platinium chlorhydric acid as a catalyst has been studied. The reaction order, activation energies and hydrid polyaddition rate constants have been found. Thermogravimetric, thermomechanical and X-ray analysis of synthesized carbosiloxane copolymers have been carried out.
