Abstract
An organic porous material having a continuous pore structure, which comprises interconnected macropores and mesopores with a radius of 0.01 to 100 .mu.m in the walls of the macropores, having a total pore volume of 1 to 50 ml/g and having pore distribution curve characteristics wherein the value obtained by dividing the half-width of the pore distribution curve at the main peak by the radius at the main peak is 0.5 or less. The organic porous material is useful as an adsorbent having high physical strength and excelling in adsorption amount and adsorption speed, an ion exchanger excelling in durability against swelling and shrinkage, and a filler for chromatography exhibiting high separation capability.
