摘要：

A water soluble silsesquioxane polymer, with different grades of 3-n-propyl-1-azonia-4-azabicyclo[2.2.2] octanechloride pendant group, was obtained using the sol-gel method and it was analyzed using infrared and thermogravimetric techniques. The silsesquioxane polymer solubility was investigated and it was related to the amount of the incorporated organic groups in the polymer network. The polymer was impregnated on the surfaces of silica, alumina and silica modified with alumina (Al/SiO2). The resulting dispersed polymer film was strongly adhered onto the Al/SiO2 surface.
