Opanasenko M. Structure and sorption properties of materials obtained by polymerization in silica mesoporous matrix

The work is devoted to investigation of the influence of chemical nature of monomer, spatial organization and structure of the porous matrix, conditions of polymerization and template removal on structure, adsorption properties and chemical nature of the surface of obtained polymers. Features of the matrix polymerization of DVB are determined and compared to those for bulk nontemplating polymerization. Determining properties of the silica MMS type, that influence on the structural characteristics and porous properties of polymer materials obtained by matrix synthesis are established. They are the spatial organization, the geometry of the matrix porous system, the size of exotemplate channels. Methods of synthesis of functionalized matrix composite polymers based on MMA, AN, VA and DVB have been developed. These techniques allow to obtain spatially ordered porous materials with high sorption parameters (Vs to 0.55 cm3/g, SBET to 630 m2/g) and high sorption capacity for Pb2+ cations (up to 1.1 mekv Pb/g) for adsorption from dilute aqueous solutions.
