Monolithic porous molded article production, used for chromatographic separation of substances, comprises repeated filling of gel mold with monomer sol, polymerization and aging gel

摘要

The production of monolithic porous molded articles that fully fill their gel mold comprises: (A) preparation of a mold; (B) filling the gel mold with monomer sol; (C) polymerization of the monomer solution; (D) aging of the resulting gel to form pores; and (E) complete filling of the remaining dead volume with further monomer sol and repeating step (C) and (D). An Independent claim is included for the resulting monolithic porous article comprising at least a core of porous monolithic material.
