摘要： Carborane-siloxane polymers are conveniently prepared by the polymerization of a carborane disilanol and either a silyl diamine, a ureido-silane, or a silyl dicarbamate. The resulting linear polymers are characterized by relatively high molecular weights and are elastomeric in nature. These gumstocks are compounded with suitable fillers and additives and fabricated into cured elastomeric articles. The carborane-siloxane elastomers exhibit excellent high temperature properties which render them especially useful for a wide variety of applications, such as gaskets, seals, wire and cable insulation and the like.

摘要： A process is provided for producing a mixture of aromatic sulfonyl chlorides and aromatic sulfones substantially free of the corresponding aromatic sulfonic acids and their anhydrides, which comprises the steps of (a) reacting a monosubstituted benzene such as monochlorobenzene with sulfur trioxide in the presence of at least about 15 mole percent to about 50 mole percent of thionyl chloride, based on the sulfur trioxide, at a temperature from about the freezing point of the reactants to about 40.degree. C.; (b) adding to the reaction mixture of step (a) at least about 60 mole percent thionyl chloride, based on the sulfur trioxide, and preferably a small catalytic amount of dimethylformamide, wherein the total thionyl chloride in the reaction mixture is at least about 110 mole percent, based on the sulfur trioxide, while maintaining the reaction mixture at a temperature between about 25.degree. C. and 70.degree. C.; and then (c) continuing the reaction up to a temperature of about 160.degree. C.
