Abstract
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.
