Abstract (en)

[origin: WO9822197A1] A water insoluble polymeric composition which is a reaction product of a cyclodextrin monomer and a polyfunctional crosslinker from the group of polyisocyanates, dihalohydrocarbons, and dihaloacetylhydrocarbons is disclosed together with a process for removing a target organic compound from an aqueous composition including contacting the aqueous composition containing a target organic compound with a water insoluble cyclodextrin polymer which is the reaction product of a cyclodextrin monomer and a polyfunctional crosslinker from the group of polyisocyanates, dihalohydrocarbons, and dihaloacetylhydrocarbons for time sufficient to form a reaction product between the water insoluble cyclodextrin polymer and the target organic compound whereby the concentration of the target organic compound in the aqueous composition is reduced. Organic chromophores added to the water insoluble cyclodextrin polymers can provide organic nonlinear optical materials.
