    • A composite hollow fiber membrane which is excellent in permeability and selectivity relative to gas- and vapor-phased organic compounds and has an improved membrane area per unit volume at the same time is provided. A composite hollow fiber membrane for separating gas- and vapor-phased organic compounds comprises a polymer coating layer formed by coating a polymer solution comprising 10 to 30 wt.% of a siloxane-based polymer in which a double bond of a vinyl group-substituted polysiloxane polymer is crosslinked with a silane group of a polyhydrosiloxane polymer by hydrosilylation reaction on a surface of a hollow fiber microporous support with a pore size ranging from 3 to 30 nanometers and a permeability ranging from 5000 to 10000 GPUs(Gas Permeation Units). The polymer coating layer has a thickness of 2 to 10 mum. The siloxane-based polymer is obtained by crosslinking 80 to 90 wt.% of the vinyl group-substituted polysiloxane polymer with 10 to 20 wt.% of the polyhydrosiloxane polymer.

    • A mass production method for asymmetric high molecular hollow fiber membrane for gas separation is provided to avoid the use of volatile additives for reducing a time for removing foams from a high molecular solution, thereby realizing high speed spinning, and to realize asymmetric structure with a porous inner layer and a high transmissivity and high selectivity outer selection layer, thereby realizing separation of various gas with high efficiency. In a mass production method for asymmetric high molecular hollow fiber membrane for gas separation, 25-40wt% concentration of high molecules selected from polysulfone, polyethersulfone, polyimide, polyetherimide, polybenzimidazole, and polyamide is dissolved in a good solvent, of which a boiling point is 150-210‹C. An inside coagulant is formed of a good solvent having a boiling point in the range from 150 to 210‹C and a nonsolvent having a boiling point in the range from 80 to 290‹C. By contacting the result solution and the inside coagulant, insides of hollow fibers are coagulated. During the contact, spinning is carried out at a speed of 30-80m/min at a temperature of 80-200‹C for producing the hollow fibers. After drying the hollow fibers, surface of the hollow fibers are coated by a poly-dimethylsiloxane solution.
