专利号:US-7576169-B2 优先权日:2003-10-23 标 题:Facile synthesis of polyhedral silsesquioxane anions and use thereof 发明人:HASEGAWA ISAO; LAINE RICHARD M; ASUNCION MICHAEL Z; TAKAMURA NORIHIRO 权利人:UNIV MICHIGAN 摘要:Polyhedral silsesquioxane anions are economically prepared by reaction of a silica source derived from combusted organic material with a quaternary ammonium hydroxide compound. Reaction of the resulting anions with chlorosilanes may be effected in near stoichiometric fashion in organic solvent containing reactive quantities of organic acids such as formic acid. The functional groups on the resulting functionalized silsesquioxanes may be substituted for other functional groups by reaction with di- or polysiloxanes in the presence of a synthetic ion exchange resin.

The compound has formula (R 1 2 )N—C(â•?O)O—Si(R 2 2 )-D-Si(OR 4 ) 3 , where R 1 may be hydrogen, methyl, or ethyl; R 2 may be methyl, R 4 may be methyl, and each instance of D is a linear or branched alkylene group such as —CH 2 —CH 2 — and —CH(CH 3 )—. The compound may be used to cap silanol moieties in a silanol-functional polyorganosiloxane to produce a polyalkoxy-functional polyorganosiloxane. The polyalkoxy-functional polyorganosiloxane may be used as a crosslinker in a moisture curable room temperature vulcanizing (RTV) silicone composition.
