    摘要: PROBLEM TO BE SOLVED: To provide novel finely composed organic/inorganic hybrid materials. SOLUTION: Organic carboxylic acids modified with alkoxy group containing silane are provided by an epoxy ring opening etherification reaction of organic carboxylic acids having from 8 to 25 carbon atoms (1) with a partial condensation product of an alkoxysilane containing glycidyl ether group (2) obtained by a dealkoholization reaction of glycidol (A) with a partial condensation product of an akoxysilane (B). A method of manufacturing the organic carboxylic acids is also provided.

    摘要: PROBLEM TO BE SOLVED: To provide a method for producing a nanoporous silicone resin useful for forming a low permittivity film for an electric insulation coating on an electronic device. SOLUTION: An alkylhydridosiloxane resin which comprises at least 5% silicon atom substituted with at least one 8-28C alkyl group, at least 45% silicon atom bonded to a hydrogen atom and the residual bond of the silicon atom bonded to an oxygen atom is heated to a sufficient temperature to cure the 8-28C alkyl substituent group and to perform a thermal decomposition so as to form the objective nanoporous silicone resin thereby.

    摘要: PROBLEM TO BE SOLVED: To obtain a sol material preservable at room temperature, capable of prolonging the shelf life and rapidly making a formed dielectric film rapidly gel by adding an additive capable of controlling the particle diameter and simultaneously modifying the surface to a starting raw material in a synthetic process for the sol material. SOLUTION: A starting raw material containing (A) 2-60 pts.wt. of a silicon alkoxide (e.g. tetraethyl orthosilicate), (B) 20-98 pts.wt. of an alcohol (e.g. methanol or ethanol), (C) 0.5-50 pts.wt. of an aqueous medium (e.g. deionized water), (D) 0.0001-10 pts.wt. of a base (e.g. hydroxylamine) and (E) 0.001-30 pts.wt. of at least one kind of additive selected from the group consisting of the formula R'nSi(OCH3)4-n, the formula R'nSi(OC2H5)4-n (R' is H, phenyl, a 1-20C alkyl or the like; n is 0-3) or the like (e.g. methyltriethoxysilane or benzoic acid) is hydrolyzed and condensed to thereby afford the objective sol material.
