The reaction of hydride addition of α,ω-bis(trimethylsiloxy)methylhydridesiloxanes with allyl glycidyl ether in the presence of platinum chlorohydric acid and Pt/C at the 1:30 ratio of initial compounds has been studied. It was established that when the reaction proceeds without solvent, three-dimensional systems are obtained. The optimal condition of hydride addition reaction, concentration of the solution, the reaction temperature have been determined. The reaction order, activation energy and hydride addition rate constants were found. In the case of platinum chlorohydric acid hydride addition proceeds with inductive period, and faster than in the case of the catalyst platinum on the carbon Pt/C. The reactions of primary and secondary amines with epoxy groups containing organosiloxanes were carried out and comb-type organosiloxanes with aminohydroxy groups in the side chain have been obtained. After protonation of amino nitrogen groups in the side chain water soluble organosiloxane oligomers were obtained. The structure of all synthesized comb-type organosiloxanes were determined by IR, 1H and 13C NMR spectra data. |
