Abstract:
A method for producing a hydrosilyl group-containing organic silicon resin of formula (6) in a solid form, wherein after formulae (1) to (3) are hydrolyzed in the presence of an acid catalyst, hydrolysis is carried out by adding hydrosilyl group-containing organic silicon compounds of formulae (4) and (5), followed by neutralization by a base catalyst with the amount thereof being more than a molar equivalent of the acid catalyst, and then by condensation. By so doing, deactivation amount of the hydrosilyl group can be reduced, so that the method for producing the hydrosilyl group-containing organic silicon resin, which is in a solid form without a solvent and to which a hydrosilyl group can be introduced quantitatively and in a large quantity, is provided, R 1 3 SiOSiR 1 3   (1) R 1 3 SiX 1   (2) SiX 2 4   (3) H n R 2 3-n SiOSiR 2 3-n H n   (4) H n R 2 3-n SiX 3   (5) (R 1 3 SiO 1/2 ) a (H n R 2 3-n SiO 1/2 ) b (SiO 2 ) c (R 4 SiO 3/2 ) d   (6)

Claim (Index 7):
A method for producing a hydrosilyl group-containing organic silicon resin, wherein\n after a mixture of one, or two or more of organic silicon compounds represented by following general formulae (1) and (2) with any one or more of a hydrolysable silane represented by following general formula (3), a partial hydrolysis condensate of the hydrolysable silane, and a metal salt of the hydrolysable silane is hydrolyzed in a presence of an acid catalyst, to a hydrolyzate thereby obtained, one, or two or more of hydrosilyl group-containing organic silicon compounds represented by following general formulae (4) and (5) is added, which is then followed by re-hydrolysis, and thereafter, neutralization is done by adding a base catalyst with an amount of more than a molar equivalent of the acid catalyst, which is followed by condensation to obtain a hydrosilyl group-containing organic silicon resin represented by following average composition formula (6), which contains a Q-unit (SiO 2 ) and an M-unit ((R 1 3 SiO 1/2 ) and (H n R 2 3-n SiO 1/2 )) as essential components, and which is in a solid form without a solvent,\n R 1 3 SiOSiR 1 3 \u2003\u2003(1) \n R 1 3 SiX 1 \u2003\u2003(2) \n wherein R 1  may be the same or different with each other, representing an unsubstituted or substituted monovalent hydrocarbon group; and X 1  represents a hydrolysable functional group,\n SiX 2 4 \u2003\u2003(3) \n wherein X 2  represents a hydrolysable functional group,\n H n R 2 3-n SiOSiR 2 3-n H n \u2003\u2003(4) \n H n R 2 3-n SiX 3 \u2003\u2003(5) \n wherein R 2  may be the same or different with each other, representing an unsubstituted or substituted monovalent hydrocarbon group; X 3  represents a hydrolysable functional group; and 1\u2264n\u22643, and\n (R 1 3 SiO 1/2 ) a (H n R 2 3-n SiO 1/2 ) b (SiO 2 ) c (R 4 SiO 3/2 ) d \u2003\u2003(6) \n wherein R 1 , R 2  and \u201cn\u201d represents the same as before; R 4  represents an unsubstituted or substituted monovalent hydrocarbon group; and 0<a\u22641.5, 0.2\u2264b\u22641.5, 0<c\u22641.0, 0\u2264d\u22641.5, and 0.5\u2264a+b/c\u22641.0.
