Abstract
New highly thermally stable carboranylmethyl-containing diorganosiloxane polymers were obtained by polycondensation of equimolar amounts of 1.7-bis[hydroxy(dimethyl)silylmethylene]-m-carborane and bis(dimethylamino)diorganosilanes. It was shown that replacement of 24 to 33 mol % of dimethylsiloxane units in the polymer backbone by methyl(phenyl)siloxane or diphenylsiloxane units containing bulky phenyl groups results in the formation of only amorphous polymers. The polymers are readily soluble in organic solvents and have high thermal stability.
