Abstract
One embodiment of the invention comprises an ion exchange composition formed by reacting unsaturated carbon to carbon moieties pendant from derivatized ion binding cryptands with a support substrate under free radical activation conditions to form a covalent bond therebetween. In another embodiment, a cryptand ion exchange composition is made by covalently bonding unsaturated carbon to carbon moieties pendant from a derivatized ion binding cryptands with unsaturated carbon to carbon moieties pendant from a support substrate under free radical activation conditions to form covalent bond.
