FIELD: textiles, paper.
SUBSTANCE: hollow fiber comprises a polymer derived from a polyimide precursor, moulded from a spin dope containing polyamine acid, and the hollow fiber has a cavity located in the center of the hollow fiber; macropores located around the cavity, and the mesopores and pikopores located around macropores where the pikopores are three-dimensionally interconnected to form a three-dimensional network structure. Polyamine acid contains a repeating unit derived from an aromatic diamine, comprising at least one functional group, which is in the ortho position with respect to the amino group and the dianhydride.
EFFECT: obtaining of hollow fiber with high permeability and good selectivity for the manufacture of membranes for gas separation.
