The mesoporous silicas of well organized structure were synthesized by applying three different block copolymers of poly-(ethylene oxide)-poly-(propylene oxide)-poly- (ethylene oxide) (PEO-PPO-PEO) type as templates. The properties of Pluronic aqueous solutions were studied by applying the viscosimetric measurements. The structure characteristics of the obtained materials were analyzed using nitrogen adsorption/desorption isotherms and X-ray diffraction data. The effect of structure and properties of the Pluronic type template on the formation of porosity of mesoporous silicas is discussed.
