Abstract

Abstract: The hydrolysis of CH₂＝CHSi(OEt)₃ has been studied. by ¹HNMR measurement. Thereaction was considered to be catalyzed by both H⁺ and OH^-; and the stronger the acidityor the basity, the more rapid the reaction. The reactant also influenced the hydrolysisreaction, especially in the initial period. Some information about the polymerization of thehydrolysis product of silane were obtained.

Key words: ²H NMR, vinyltriethoxysilane, strengthening agent for cement, hydrolysis, polymerization
