CAGE-TYPE SILOXANE COMPOUND CONTAINING ALKOXY GROUP, CAGE-TYPE SILOXANE COMPOUND CONTAINING SILANOL GROUP AND PRODUCTION METHODS THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a cage-type siloxane compound containing an alkoxy group or a cage-type siloxane compound containing a silanol group, wherein an alkoxy group or a silanol group is optionally incorporated in a cage-type siloxane with a controlled molecular structure.;SOLUTION: The cage-type siloxane compound containing an alkoxy group is produced by adding a dialkoxysilane of the formula: R¹R²Si(OR³)₂ [wherein R¹ and R² are each a vinyl group, an alkyl group, a phenyl group, a (meth)acryloyl group, an allyl group or a group having an oxirane ring; and R³ is a methyl group or an ethyl group] to a cage-type siloxane compound of the formula: [R¹SiO_3/2]_n [wherein R¹ is a vinyl group, an alkyl group, a phenyl group, a (meth)acryloyl group, an allyl group or a group having an oxirane ring; and n is an integer of 8-14] in the presence of a nonpolar solvent and a basic catalyst. The cage-type siloxane compound containing a silanol group is produced by hydrolyzing the cage-type siloxane compound containing an alkoxy group in the presence of an acidic or basic catalyst.;COPYRIGHT: (C)2009,JPO&INPIT
