Interpenetrating Network on the Basis of Methylcyclotetrasiloxane Matrix

Abstract

1 Hydrosilylation reaction of 2,4,6,8-tetrahydro-2,4,6,8-tetramethylcyclotetra siloxane (D 4 H ) allyl trifluoroacetate and vinyltriethoxysilane catalysed by platinum catalysts has been studied.The synthesized D 4 R,R'was analyzed with FTIR, 1 H, 13 C, and 29 Si NMR spectroscopy. Via sol-gel reactions of D 4 R,R' systems doped with lithium trifluoromethylsulfonate (triflate) solid polymer electrolyte membranes have been obtained. It has been found that the electric conductivity of the polymer electrolyte membranes at room temperature changes in the range of (4·10 -5 )-(6·10 -7 ) S/cm.
