Patent ID: 7449535

Claim:
A process of making a compound comprising the steps of: providing a carborane-siloxane precursor comprising the formula: U—(SiR 2 —O) v —SiR 2 —C b —SiR 2 —(O—SiR 2 ) w —U; wherein C b is a carboranyl group; wherein v and w are positive integers; wherein each U is an independently selected alkenyl group or alkynyl group; wherein each R is independently selected from the group consisting of alkyl, aryl, alkylaryl, haloalkyl, haloaryl, and mixtures thereof; providing a siloxane crosslinker comprising the formula: Si ⁢ ⁢ R n ″ ⁡ [ ( O - Si ⁢ ⁢ R 2 ′ ) x ⁢ H ] 4 - n ; wherein each R′ and R″ is independently selected from the group consisting of alkyl, aryl, alkylaryl, haloalkyl, haloaryl, and mixtures thereof; wherein each x is an independently selected positive integer; and wherein n is selected from the group consisting of 0, 1, and 2; and reacting the carborane-siloxane precursor with the siloxane crosslinker in the presence of a hydrosilation catalyst.
