Abstract
Abstract Organic resins with high surface areas and porosities, which are insoluble in organic solvents and contain few or no flexible groups in the resin structure, are disclosed. Also disclosed is a process for making such resins from polyfunctional aryl alkali metal compounds and a second polyfunctional monomer. Such resins are useful as absorbants.
