摘要: The effects of acid catalyst, water content and reaction temperature on the hydrolysis polycondensation phenyltriethoxysilane (PhTES) were studied using 29Si NMR spectroscopy. sol catalyzed by hydrochloric showed simultaneous progress polycondensation. In addition, rate was almost independent temperature. On other hand, in PhTES-derived mixed with an excess amount acetic as a catalyst proceeded after completion hydrolysis. acid-catalyzed system, degree largely depends
