    Abstract: Ultrafine porous polymer articles with a predetermined maximum pore radius and processes of producing such polymer articles are described wherein a thermoplastic polymer body is contacted with an aqueous solution of a selected monomer, a specified differential pressure is applied between opposite body sides, only the pores with a radius larger than the predetermined radius are wetted by the solution of the monomer, the solvent is evaporated, and the monomer is polymerized in situ. The resulting article is a composite structure consisting substantially of a first thermoplastic polymer, and a small addition of a second polymer in the former pores which were larger than the predetermined maximum pore radius.
