Abstract
A method is disclosed for making an organoalkoxysilane/metal oxide sol-gel composition in an essentially aqueous medium by partially hydrolyzing an organoalkoxysilane with a limited amount of water which is essentially completely consumed in the hydrolysis reaction, adding a metal alkoxide of titanium or zirconium to the essentially anhydrous partially hydrolyzed organoalkoxysilane, completely reacting the metal alkoxide with the partially hydrolyzed organoalkoxysilane to form an oxide network and then completely hydrolyzing the composition in water.
