STUDY OF CROWN-CONTAINING POLYMER DISTRIBUTION OVER A CARBON SUPPORT

A study of crown-containing polymer distribution over a mesoporous car bon support is performed, making use of a comparative analysis of nitr ogen sorption isotherms on the support and the supported catalysts. Th e polymer content partition between the surface and the pore volume of the support is determined, and the correlation between the catalytic activity of the system in the reaction 1-bromooctane+KI and the fracti on of the bulk polymer filling the pores is established. Some potentia lities of the comparative analysis of sorption isotherms are demonstra ted by this study.
