Synthesis and thermal degradation mechanism of polyorganocarboranesiloxanes containing m-carboranylmethyl unit

This paper reports a high-yielding, efficient and facile method in preparing monomers, namely 1,7-bis(hydroxyl(dimethyl)silylmethyl)-m-carborane (M1), 1,7-bis(diethylamino(dimethyl)silylmethyl)-m-carborane (M2), 1,3-dimethyl-1,3-diphenyl-siloxanediol (M3) and diethylaminomethylphenylsilane (M4). The reaction of M2 and M3 to get polymer P1, and the reaction of M1 and M4 to get polymer P2 which has a promising lead in searching for materials with...
