At present development of new effective methods for energy storage and conversion is an important problem for scientists. Thus, very important problem is research and progress of low cost, readily acceptable, long life, high energy storage or other type devices. Heterofunctional condensation reaction of 2-(2-(2-methoxyethoxy)ethoxyl)ethanol (triethylenegly¬colmonomethylether) with vinyltrichlorosilane at 1:3.2 ratio of initial compounds have been carried out and transparent viscous tris(monomethylethertri-ethylene glycol)vinylsilane.Hydrosilylation reaction of D4H with tris(monomethylethertri-ethylene glycol)vinyl silane and vinyltriethoxysilane at 1:4.2 and 1:3:1ratio of initial compounds have been carried out in solution, in the presence of Karstedt’s catalysts, at 80-900C temperature have been carried out and D4R and D4RR’ type organocyclotetra-siloxanes have been obtained. Polymerization reaction of D4R in the presence of anhydrous potassium hydroxide have been carried out and comb-type methylorgano-siloxanes polymer have been obtained. The structure of polymers have been determined by FTIR spectral analysis. Via sol gel reaction of obtained polymer and D4RR’ organocyclotetrasiloxane solid polymer electrolyte (PE) membranes have been obtained. Since the PE membranes obtained from polymers were hard and breakable we did not have to be able to measure their ion conduction. It was shown that ion conductivity of PE membranes obtained from D4RR’ changes in the range 9x10-5 - 7x10-8 S/ cm.
