Permeability coefficients of Hz, Oz, and Nz were measured under 10 atm at the temperature from ambient temperature up to 15OoC in a series of structurally different aromatic homoand copolyimides, which were prepared from 4,4'-oxydianiline (ODA) or 4,4'-methylene dianiline (MDA) with various aromatic
