Nature of bridge little impact on the character of adsorption and acidic functional groups available for adsorption interactions with electron-donor molecules. 2. Microspheres obtained by template methods on the basis of TEOS have high values of specific surface area (747 m2/g),but due to lower content of functional groups and significant difference in texture compared with bridged polysilsesquioxanes showing lower adsorption activity with respect to the molecules of TEA.
