Abstract: A filter material contg. polyarylene ethers is used to remove NO2. Also claimed is a filter material contg., in addition, an oxidising agent with a redox potential of at least 0.96V. Also claimed are filters contg. such filter materials and the process of producing gases free of NO and NO2 by bringing the gases in contact with such filter materials.

Abstract: A filter material for removing components from gases and liqs. is based on a porous polymer (A) with a specific surface (BET) of more than 2 m /g. Also claimed is a process for the prodn. of polymer (A) from a polyarylene sulphide (PAS) or polyarylene ether (PAE), by phase inversion from soln..
