ABSTRACT
Abstract-The reactivity of silanes in waterborne systems was studied using model compounds. Vinyltrialkoxysilanes were used to investigate the effects of the leaving group on the rates of silane hydrolysis. The alkoxy groups were methoxy, ethoxy, 2-propoxy and 3-oxabutoxy. The acid-catalyzed rates of hydrolysis for these silanes were measured under pseudo-first-order conditions in an aqueous acetone solution at 22°C. Steric and polar characteristics of the alkoxy leaving group were found to affect the hydrolysis rates.
