摘要

A composite diaphragm for gas separation with a three-layer structure, consisting of: A) a supporting diaphragm layer of porous polymer; B) a non-porous, gas-permeable intermediate layer; C) a perm-selective layer of regularly arranged organic molecules with a layer thickness of 3 to 100 nm; where layers (A) and (C) envelop the intermediate layer (B). The perm-selective layer (C) is formed of at least one regularly arranged polymer consisting of at least one of the unsaturated monomers (I) and (II), in which R<1> and R<2> are independently CH3 and C2H5 and X is H, CH3, Cl, F and CN.
