Porous polyimide raw film, method for producing the same, and composition |
| abstract |
(Problem) Provided the porous polyimide film fabric excellent in tensile strength and bending strength, its manufacturing method, and the composition used preferably for its manufacture. (Solution) Porous polyimide film fabric having a tensile strength of 45 MPa or more as specified by ASTM standard D638. Porous polyimide film original material containing the polyimide containing the structural unit represented by following formula (1-1) and the structural unit represented by following formula (1-2). (In the above formula, A 11 and A 12 each independently represent a tetravalent aromatic group derived from an acid anhydride containing an aromatic tetracarboxylic anhydride, and B 11 and B 12 are each independently derived from aromatic diamine. Represents a divalent diamine residue and at least one selected from the group consisting of A 12 and B 12 contains a divalent spacer group in its structure) |
