Abstract
The reaction of catalytic dehydrocondensation of dihydroorganocyclotet ra(hexa)siloxanes with dihydroxyorganocyclotetra(hexa)siloxanes in the presence of platinochlorohydric acid and of anhydrous powder-like cau stic potassium has been studied. Reaction order, activation energies a nd dehydrocondensation rate constants were found. Thermogravimetric, t hermomechanical and X-ray studies of the synthesized polymers were car ried out.
