摘要：

The thermal properties of new anion exchangers consisting of silica core and organic layers grafted onto their surface were evaluated by thermogravimetry and differential scanning calorimetry. The anion exchangers were prepared by chemical modification of bare silica gel. The support was coated with polymeric layers formed by condensation polymerization of primary amines with diepoxides. Synthesized copolymers of methylamine and 1,4-butanedioldiglycidyl ether have a dendrimer structure. By TG/FTIR/MS, it was observed that silica-layered materials exhibited two stages of mass loss: first with T (max1) 160 A degrees C, connected with desorption of water molecules from the adsorbents surface, and then with T (max2) 390 A degrees C, connected with degradation of organic layers.
