The present invention relates to a polymeric porous material characterized in that: the porous material has a bimodal pore size distribution attributable to macropores having a pore size of at least 50 nm and mesopores having a pore size of from 2 nm to less than 50 nm, the proportion of the specific surface area of the macropores to the specific surface area of all pores of the porous material is at least 10%, and the porous material is produced by (1) polymerizing a monomer in the presence of a polymerization initiator using as a porogen a solution obtained by dissolving a polymer having a weight-average molecular weight of at least 100,000 and a molecular weight distribution Mw/Mn of not more than 1.5 in a good solvent for the monomer, and (2) removing the porogen from the resultant product.

Porous polymer and process for producing the same

To obtain a non-particle-aggregation-type organic polymer monolith separation medium, there is provided a monolith separation medium comprising a skeletal phase and pores being continuous in the form of three-dimensional network, which skeletal phase on its surface has a functional group permitting introduction of a new functional group. The skeletal phase has a non-particle-aggregation-type co-continuous structure having an average diameter of submicron to micrometer size, and is constituted of an addition polymer from an epoxy compound of bi- or higher functionality and an amine compound of bi- or higher functionality. Further, the skeletal phase is enriched in organic matter and does not contain any carbon atoms derived from aromatic series.

Monolith separation medium for chromatography and process for producing the same

A face categorizing apparatus for categorizing contours of a face of an examined subject is disclosed that includes image capturing means for capturing a face image of the face of the examined subject; control means for controlling operations for categorizing the face of the captured face image into one of at least four predetermined types of categories based on at least two indices including facial space and facial depth/bone structure/fleshiness; and indication means for indicating a categorization result of categorizing the face by the control means on a map having the four predetermined types of categories positioned at corresponding quadrants of a plane coordinate system.

A monolith separation medium comprising a skeletal phase and continuous pores forming a three-dimensional network structure, which has a functional group enabling the introduction of a new functional group on the surface of the skeletal phase. The skeletal phase has an average diameter of a submicron to micrometer size and is in a co-continuous structure of the non-particle-aggregation type. It is composed of an addition polymer of 1,3-bis(N,N'-diglycidylaminomethyl)cyclohexane as an epoxy compound with a bifunctional or higher amine compound, is rich in organic matters and is free from any aromatic-origin carbon atom. Thus, it is an organic polymer monolith separation medium of the non-particle-aggregation type.

A porous object comprising a three-dimensional network skeleton of a cured epoxy resin and having interconnecting pores, characterized in that the three-dimensional network skeleton forms a non-particle-aggregation type porous object constituted of a three-dimensional branched columnar structure, the proportion of aromatic-ring-derived carbon atoms to all the carbon atoms as a component of the cured epoxy resin is 0.10-0.65, and the porous object has a porosity of 20-80% and an average pore diameter of 0.5-50 &#x3bc;m.

Porous cured epoxy resin

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.

Polymer packing material for liquid chromatography and a producing method thereof

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.

Polymer packing material for liquid chromatography and a producing

Polymer particles having a hydrophobic core and various surface functional groups, particularly hydrophilic and chiral surface functional groups, are produced by adding a non-emulsified functional polymerizable monomer to the aqueous phase of a dispersion of soluble polymer particles which have previously been swollen with an emulsified-monomer and polymerizing the monomers. Preferably the particles are uniform macroporous beads.

Preparation of surface-functional polymer particles

A process for producing macroporous polymer beads from a multiphase emulsion using soluble polymer particles as the primary porogen is disclosed. The beads produced are of uniform size and shape.
