Abstract
A graft-modified organic porous material comprising an organic porous material of 1-50 ml/g total pore volume having such an open cell structure that mesopores of 0.01-1000 .mu.m radius are present within walls between macropores communicating with each other and, provided on the surface of the organic porous material, grafted polymer chains, characterized in that the density of polymer chains is at least 0.1 polymer chain per nm.sup.2 of surface of organic porous material. Thus, there are provided a graft-modified organic porous material wherein polymer chains have been introduced at high density in surface portion of organic porous material and a process for producing the same.
