Abstract	Currently there is need for the creation of targeted membranes designed for particular separation purposes. An integrated membrane system for filtration and gas separation is widely required. Despite the active study of hundreds of polymers as potential membrane materials only a few of them are applied for the production of commercial membranes. The strict selection of polymers for membranes production does not depends only on the mass transfer properties, but also on rheological, mechanical and chemical properties, stability in process conditions and economically reasonable availability of the polymer. Poly-4-methylpentene-1 (PMP) takes special place among a number of membrane polymers as it meets the above noted requirements. The drawback of PMP application for membranes is that traditional manufacturing process of asymmetric hollow fibers (HFs) based on PMP requires the use of harmful solvents and precipitants. The manufacturing process suggested in the Project assumes the application of the melt-spinning technology for the PMP HF membrane production. Further, the published data on the parameters of gas permeability for PMP is limited. In recent years interest in PMP as a membrane material is intensified. The effect of permeable crystalline phase on the gas separation properties of PMP is systematically investigated in the framework of the grant RFBR No.15-03-03033. The theoretical and experimental analysis of PMP is aimed to determine the influence of the crystalline phase on the gas separation properties.
