CARBORANE-SILOXANE ELASTOMERS

Abstract

The synthesis of thermally stable carborane-siloxane elastomers was undertaken. Carborane and silane intermediates prepared include: neocarborane, 1,7-diallylcarborane, 1,7-bis(3-(chlorodimethylsilyl) propyl) carborane, tetramethyldisiloxane, dichlorotetramethyldisiloxane and chlorodimethylsilane. A liquid polymer was obtained by silyl hydride addition polymerization of 1,7- diallylcarborane and tetramethyldisiloxane. A homopolymer of 1,7-bis(3- (chlorodimethylsilyl) propyl) carborane prepared by hydrolysis, was obtained as a gum; copolymers of this compound with diethoxydimethylsilane and dichlorotetramethyldisiloxane, obtained by alkoxy-halogen condensation and hydrolysis respectively, were liquids of 1800 and 2500 molecular weight.
