Vinylphenyloctasilsesquioxanes
Tóm tắt
Heptavinylphenyloctasilsesquioxane and hexavinyldiphenyloctasilsesquioxane were obtained for the first time by the cohydrolysis of vinyl- and phenyltrichlorosilane. The statistical character of the distribution of the RSiO1.5 and R'SiO1.5 fragments, which is observed during the cohydrolysis of trifunctional organosilicon monomers with an equal or slightly different reactivity, is upset when forming the polyhedral SiO skeleton of these compounds.
