(57) [Summary] [Structure] Monomers and / or oligomers (A) that are polymerizable by irradiation with energy rays are compatible with the monomers and / or oligomers (A), and the monomers and / or oligomers (A) are compatible. The uniform polymerizable liquid, which is incompatible with the polymer produced by irradiating the polymer with the energy ray and is inactive to the energy ray, and a mixture of the polymer (C) and the oligomer (B), was irradiated with the energy ray. After that, the oligomer (B) or the polymer (C) is removed, a method for producing a porous polymer membrane. [Effect] The porous polymer membrane obtained by the production method of the present invention has a cross-linked structure and is therefore characterized by being excellent in strength, creep resistance, heat resistance and chemical resistance. Again 100 Since a highly viscous polymerizable solution of cps or more can be obtained, it has a feature that a hollow fiber-shaped porous membrane, a porous membrane backed by a porous support such as a nonwoven fabric, cloth, and paper can be easily produced. |
