Adsorption Studies on Organosilic Acid Polymers We present four organosilic acid polymers containing double-4-ring silicate units cross-linked at different degree by different organosilicon bridges. BET surfaces were determined and adsorption isotherms of n-hexane, benzene, nitrogen and water were measured. All polymers are hydrophobic, one of them behaves microporously, the other are unporous. With organic adsorptives, swelling and adsorption occur simultaneously. Possible relations of microporosity and structure are discussed. 相似文献
