Annotation:

Hydrosilylation reaction of 2.4.6.8-tetrahydro-2.4.6.8-tetramethylcyclotetrasiloxane (D4H) with allyl acetoacetate at 1:4.1 molar ratios of initial compounds in the presence of platinum catalysts have been studied and D4R type compounds has been obtained. Ring–opening polymerization reaction of D4R in the presence of catalytic amount of powder-like potassium hydroxide has been carried out. Linear methylsiloxane oligomer with regular arrangement of propyl acetoacetate groups in the side chain has been obtained. Via sol-gel processes of doped with lithium trifluoromethylsulfonate (triflate) or lithium bis(trifluoromethylsulfonyl) imide oligomer systems solid polymer electrolyte membranes have been obtained. The electro conducting properties of obtained polymer electrolyteshave been studied.
