    摘要: A method of producing a polymer packing material for liquid chromatography includes the steps of swelling seed polymer particles to form swelled particles, polymerizing monomers in the swelled particles under existence of diluent, and removing the diluent to form porous polymer particles, wherein the step of polymerizing the monomers is conducted under existence of a compound having a conjugated double bond not reactive with the monomers and having a molecular weight of 100-500. Alternatively, the polymerization process may be conducted by an oxidation reduction polymerization process. Further, the porous polymer particles obtained after removal of the diluent may be subjected to a heat treatment process at a temperature of 100.degree. C. or higher.

    摘要: There are disclosed a polymer packing material suitable for liquid chromatography and a producing method thereof. The polymer packing material having a polymer particle based on a styrene skeleton with monodispersed particle distribution can be obtained by hydrophilic treatment of an inner surface of a micropore existing in a fine pore of the polymer packing material, or subsequent introduction of a hydrophobic group into the inner hydrophilic surface by chemical modification. A method of producing the polymer packing material suitable for liquid chromatography includes the step of polymerizing glycerol dimethacrylate as a crosslinking agent and 2-ethylhexl methacrylate as a monomer according to a two-step swelling polymerization process. Alternatively, the producing method includes the step of crosslinking and polymerizing only glycerol dimethacrylate to form a polymer, and introducing the hydrophobic group into the polymer by chemical modification.

    摘要: A packing material for a liquid chromatograph is provided particularly to be used for separating polycyclic aromatic compounds. The packing material is prepared by treating a base material of the packing material with a coupling agent of the formula (I): ##STR1## wherein Aro is an aromatic moiety, R.sup.1 and R.sup.2 are independently alkyl, alkenyl, aryl, lower alkoxy group, or halogen atom, R.sup.3 is a lower alkoxy group or halogen atom. Since an aromatic moiety within one molecule is immobilized through many functional groups on the surface of the base material, the packing material has stable and excellent separating properties.
