1. Способ формования асимметричных газоразделительных и первапорационных мембран в виде полых волокон путем пропускания фильтрованных амидных растворов (в диметилформамиде, диметилацетамиде, N-метилпирролидоне) стеклообразных полимеров, преимущественно полисульфонов и полиэфирсульфонов, заключающийся в формовании раствора полимера через фильеру, осаждении его в мягком осадителе с получением волокна, удалении мягкого осадителя, осаждении волокна в жестком осадителе и его отмывке, отличающийся тем, что операции формования волокна из раствора и его осаждение с помощью мягкого осадителя производят одновременно.1. A method of forming asymmetric gas separation and pervaporation membranes in the form of hollow fibers by passing filtered amide solutions (in dimethylformamide, dimethylacetamide, N-methylpyrrolidone) of glassy polymers, mainly polysulfones and polyethersulfones, which consists in forming a polymer solution through a die, and it is precipitated with mild precipitation obtaining fiber, removing the soft precipitant, deposition of the fiber in the hard precipitant and washing it, characterized in that the operation of forming the fiber from astvora and precipitation using a precipitant soft performed simultaneously. 2. Способ по п. 1, отличающийся тем, что регулируют время от момента начала формования волокна с осаждением мягким осадителем до момента попадания волокна в жесткий осадитель путем изменения расстояния между фильерой и поверхностью жидкости жесткого осадителя и создания встречного (по отношению к движению волокна) турбулентного потока жесткого осадителя. 2. The method according to p. 1, characterized in that it regulates the time from the moment the fiber is formed with the deposition of a soft precipitator until the fiber enters the hard precipitator by changing the distance between the die and the liquid surface of the hard precipitant and creating an oncoming one (with respect to the fiber movement) turbulent flow of hard precipitant.
