Polymeric membrane materials: New aspects of empirical approaches to prediction of gas permeability parameters in relation to permanent gases, linear lower hydrocarbons and some toxic gases

►New N-dimensional approach for prediction of gas permeability parameters of polymers ►Corrected Stuart's diameters of penetrant's molecules can be used for calculation of permanent gases, linear lower hydrocarbons and some toxic gas permeability for polymers when these data are even unavailable. ►Expected gas permeability for set of modern polymers is calculated.
