SEPARATION MEMBRANE, COMPOSITE SEPARATION MEMBRANE AND PROCESS FOR PRODUCING SEPARATION MEMBRANE

摘要

The separation membrane of the present invention includes: a separation function layer including a high-molecular polymer as a matrix and an amine compound represented by the formula [I] and/or [II] below; and hydrophobic layers arranged on both faces of the separation function layer. The separation function layer includes a crack inhibitor.
(In the formula, A 1 represents a divalent organic residue having 1 to 3 carbon atoms, and n represents an integer of 0 or 1.)
(In the formula, A 2 represents a divalent organic residue having 1 to 3 carbon atoms, and n represents an integer of 0 or 1.)
