<p><P>PROBLEM TO BE SOLVED: To solve a problem that it is necessary to suppress the radical polymerization of monomers that is a competitive reaction when a graft chain suitable as an adsorption film is formed to a porous film. <P>SOLUTION: The method which introduces a graft chain to a porous substrate including a polymer, includes: an immersion step in which the porous substrate is immersed in a solution including a radically polymerizable monomer; and an irradiation grafting step in which the porous substrate is irradiated in an immersed state, the radically polymerizable monomer is performed with graft polymerization to the porous substrate, and the graft chain is formed to the porous substrate, wherein the solution including the radically polymerizable monomer includes a solvent containing 40-70 vol% of a primary or secondary univalent lower alcohol. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
