Their stability was tested using a novel, multichannel measuring system, which is based on pressure differences. This measuring system is suitable to determine the changes in permeability of polymer membranes. The damaging effects of H2S, BTX and n-dodecane were investigated in terms of polyimide gas separation membranes using nitrogen gas. }, number={1}, journal={Hungarian Journal of Industry and Chemistry}, author={Nemestóthy, Nándor}, year={2017}, month={Nov.}, pages={5–8} }
