Synthesis of Polymolybdenophenylsiloxane

摘要

Polymolybdenophenylsiloxane containing Mo(V)atoms and preserving the Si:Mo ratio equal to that in the starting mixture was prepared by the reaction of molybdenum(V)oxychloride dimethyl sulfoxide crystal solvate with sodium polyphenylsiliconate in the presence of dimethyl sulfoxide.The influence of the reaction conditions on the nature and yields of products was examined.Experiments on thermal oxidative degradation of polymolybdenophenylsiloxane showed that it is more stable compared to the previously studied polymetalloorganosiloxanes containing various d elements with the stoichiometric Si:metal ratio.
