FIELD: gas industry.
SUBSTANCE: group of inventions refers to the area of non-cryogenic separation of gas mixtures. Composition contains a polymeric material - soluble polyarylsulfone, solvents - n-methylpyrrolidone, dimethylformamide, tetrahydrofuranine and nonsolvent - glycerin. Method comprises a spinning solution manufacturing, an internal water and n-methylpyrrolidone precipitant solution, hollow fiber membrane drying, hollow fiber membrane forming that is formed in the precipitation bath through the air gap.
EFFECT: increase in the selectivity and mechanical strength of the hollow fiber gas separation membrane is achieved.
