Abstract
The present invention provides a separation material that comprises porous polymer particles comprising a styrene-based monomer as a monomer unit; and a coating layer comprising a macromolecule having hydroxyl groups, which covers at least a portion of the surface of the porous polymer particles, and the separation material has a 5% compressive deformation modulus of 100 to 1,000 MPa, and has a mode diameter in the pore size distribution of 0.1 to 0.5 μm.
