PROBLEM TO BE SOLVED: To provide a modified polyketone film, finely porous film excellent in water wettability and water impregnability, because excellent water affinity is imparted to a polyketone molded article, and to provide a thermally modified polyketone molded article, especially a finely porous thermally modified polyketone film, having solvent resistance at a high temperature, especially high temperature resistance to the electrolytes of capacitors or batteries. SOLUTION: The modified polyketone molded article is obtained by treating a polyketone molded article with a reactant capable of reacting with the carbonyl groups of the polyketone molded article. The thermally modified polyketone molded article is obtained by thermally treating the modified polyketone molded article at 110 to 270°C. COPYRIGHT: (C)2010,JPO&INPIT
