Abstract:
1. A polymeric porous material wherein (a) the porous material has a bimodal pore size distribution attributable to macropores having a pore size within a range from 1 to 2 μm and mesopores having a pore size of from 2 nm to less than 50 nm, (b) 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%, (c) the porous material has a uniform structure comprising a three-dimensional continuous network skeleton structure with pores of a regular bimodal pore size distribution with symmetrical peaks of mesopore and macropore size regions and a permeability suitable for flowing through a mobile phase liquid, wherein the pores are obtained by a phase separation via viscoelastic effect of a porogen solution, and (d) the porous material is produced by
