PROBLEM TO BE SOLVED: To provide a porous material high in high-temperature reliability and excellent in chemical resistance by using a material composed of a saturated hydrocarbon. SOLUTION: A porous resin material comprises a cyclic conjugated diene- based polymer represented by the formula (1) [-(A)a-(B)b-(C)c-(D)d-(E)e-] [wherein (A), (B), (C), (D) and (E) represent respective molecular structure units composing the principal chain of the polymer; (A) is a cyclic conjugated diene-based monomer; (B) is a chain conjugated diene-based monomer; (C) is a vinyl-based aromatic monomer; (D) is a polar monomer; (E) is a molecular structure unit derived from ethylene and/or anα-olefin-based monomer; a, b, c, d and e represent the weight percent of respective molecular structure units contained in the principal chain of the polymer; a+b+c+d+e=100; and 0.5<=a<=100] and the formula (1) represents the composition formula of the polymer. |
