ABSTRACT:
A method of co-hydrolyzing silanes of the formulas HSi(OR).sub.3 and Si(OR).sub.4 to form a soluble resinous co-hydrolysate is disclosed. The method comprises hydrolyzing the silanes with water in an acidified oxygen containing polar organic solvent. The invention also relates to the soluble co-hydrolysates formed thereby as well as the method of using the co-hydrolysates to provide coatings on various substrates, including electronic devices.
