Synthetic example S-1
[0305] [Hydrolysis and condensation reaction]
[0306] In a reaction vessel with a stirrer, a thermometer, a dropping funnel and a reflux condenser, 73.9 g of 2-(3,4-epoxycyclohexyl)ethyltrimethoxysilane (ECETS ) and 24.8g of γ-methacryloxypropyltrimethoxysilane (GMPTS) (ECETS:GMPTS=75:25 (molar ratio)) and 500g of methyl isobutyl ketone as a solvent and as a catalyst 10.0 g triethylamine, mixed at room temperature. Next, after adding 100 g of deionized water dropwise from the dropping funnel over 30 minutes, it was reacted at 80° C. for 6 hours while stirring under reflux. After the reaction, the organic layer was taken out, washed by 0.2% by weight of ammonium nitrate aqueous solution until the washed water was neutral, and the solvent and water were distilled off under reduced pressure to obtain a hydrolysis condensate with epoxy groups, which was viscous transparent liquid.

[0311] [Hydrolytic Condensation Reaction] and [Reaction of Hydrolytic Condensate with Epoxy Group and Carboxylic Acid]
[0312] In the above-mentioned Synthesis Example S-1, the hydrolyzable silane compound and carboxylic acid of the kind and amount described in Table 1 were respectively used, and the hydrolytic condensation reaction and the hydrolytic condensation product and carboxylic acid were carried out in the same manner as Synthesis Example S-1. After the reaction, polyorganosiloxanes (PS-2) to (PS-6), (PS-10), (PS-11) and (PS-16) as (A) the first polymer were obtained respectively. The yields and Mw of these polyorganosiloxanes are combined in Table 1 and shown. In addition, in Synthesis Examples S-3 to S-5 and S-16, two kinds of carboxylic acids were used for each. Synthesis Example S-6 is a comparative synthesis example.
