CARBORANE-SILOXANE ELASTOMERS

Abstract

The carborane silane monomers, bis(1-chlorodimethylsilyl-o-carboran- 2-yl) propane and bis(1-methoxydimethylsilyl -o-carboran-2-yl) propane, were synthesized and copolymerized to a carborane polysiloxane. Thermal characterization of the polymer by TGA and DTA in air and nitrogen indicated thermal stability to 350 deg C with no oxidation evident until over 400 deg C. The thermal data illustrate the 'protective action' of carborane and its ability to stabilize neighboring groups to thermal oxidative degradation.
