摘要

The hydrosilylation reactions of a,v–bis(trimethylsiloxy)methylhydrosiloxane with allyl butyrate and vinyltriethoxysilane catalyzed by Karstedt's (Pt_2[(VinSiMe_2)_2O]_3) catalyst, platinum hydrochloric acid (0.1 M solution in THF) and platinum on carbon have been studied. In the presence of Karstedt's catalyst the reaction order, activation energies and rate constants have been determined. The synthesized oligomers were analyzed with FTIR, ~1H, ~(13)C, and ~(29)Si NMR spectroscopy. Synthesized polysiloxanes were investigated by wide-angle X-ray scattering, gelpermeation chromatography, and DSC methods. Solid polymer electrolyte membranes have been obtained via sol-gel processes of oligomer systems doped with lithium trifluoromethylsulfonate (triflate) or lithium bis(trifluoromethylsulfonyl)imide. The dependence of ionic conductivity as a function of temperature and salt concentration has been investigated. It has been found that the electric conductivity of the polymer electrolyte membranes at room temperature changes in the range 4 × 10~(-5)–6 × 10~(-7) S/cm.
