Bromine was utilized in the presence of stoichiometric amount of pyridine to brominate silanic hydrogen of methylhydropolysiloxanes. Methylbromopolysiloxanes thus obtained and methylchloropolysiloxanes prepared from photo-chlorination of methylhydropolysiloxanes were hydrolyzed with or without methylchlorosilanes to yield new methylhydroxypolysiloxanes and branched methylpoly siloxanes. Preparation
在化学计量量的吡啶存在下使用溴来溴化甲基氢化聚硅氧烷的硅烷氢。由此获得的甲基溴聚硅氧烷和由甲基氢聚硅氧烷的光氯化制备的甲基氯聚硅氧烷在有或没有甲基氯硅烷的情况下水解,以产生新的甲基羟基聚硅氧烷和支化甲基聚硅氧烷。还报道了甲基氢环戊硅氧烷的制备。
