摘要：The polyimide resin is an asymmetric membrane containing a cross-linkedpolyimide resin formed by cross-linking with a cross-linking agent, wherein the polyimideresin is a structural unit derived from tetracarboxylic dianhydride (A) and a structural unitderived from diamine (B). The structural unit (A) includes a structural unit (A-1) derivedfrom the compound represented by the formula (a-1), and the structural unit (B) isderived from the formula (b-1). A functional group containing a structural unit (B-1),wherein the proportion of the structural unit (B-1) in 100 mol% of the structural unit (B) is0.1 to 50 mol%, and the crosslinking agent binds to a carboxy group; An asymmetricmembrane which is a compound containing two or more. (In formula (b-1), Q and Q areeach independently a group containing an aromatic group, an aliphatic hydrocarbongroup and / or an alicyclic hydrocarbon group, and X is a single bond or a specific bondGroup, p is an integer of 0 to 2, m 1 is an integer of 0 to 4, and m 2 is an integer of 0 to 4.However, when p is 0, m 1 is an integer of 1 to 4 is there.)
