4.92 g of phenyltrimethoxysilane, 72.40 g of tetraethoxysilane, 22.04 g of methyltriethoxysilane, 0.64 g of the 30% ethanol solution of triethoxysilylpropyl-3-methyl-4,5-dihydroimidazolium methanesulfonate, and 150 g of acetone were charged into a 500 mL flask to be dissolved and the resultant mixed solution was warmed while stirring the mixed solution with a magnetic stirrer to reflux. Next, 33.10 g of 0.01 M hydrochloric acid was added to the mixed solution. The mixed solution was subjected to the reaction for 240 minutes and then the resultant reaction solution was cooled down to room temperature. Then, 200 g of propylene glycol monoethyl ether was added to the reaction solution, and ethanol and methanol as reaction by-products, acetone, water, and hydrochloric acid were distilled off under reduced pressure to obtain a hydrolysis-condensation product. The polymer thus obtained corresponded to Formula (VII-13):
