Catalytic dehydrocondensation of dihydroorganocyclotetra(hexa)siloxanes with dihydroxyorganocyclotetra(hexa)siloxanes in the presence of platinochlorohydric acid on anhydrous powder-like caustic potassium has been studied. High-molecular weight organosilicon polycyclic copolymers with bead-like structure having cyclotetra- and cyclohexasiloxane fragments in the chain and completely insoluble in organic solvents were synthesized. Reaction order, activation energies and dehydrocondensation rate constants were found. Thermogravimetric, thermomechanical and X-ray studies of the synthesized polymers were carried out. |
