摘要： Extrusion of hollow membranes is improved by coextruding a coating fluid layer about the extrudate of heated polymer solution with its interior lumen forming extrudate. The coating fluid is disposed between the forming hollow fiber and a cooling fluid, and controls the rate of heat transfer to afford superior control over the structure and form of the hollow fiber produced in the invention. The coating fluid is typically the same material as the cooling fluid, and often is the same material as the solvent for the polymer in the heated polymer solution.

摘要： A process for making a polymeric, porous hollow fibre (21) by heating a mixture of a thermoplastic polymer and a solvent to a temperature and for a time for the polymer and solvent to mutually dissolve, then introducing the molten mixture into an extrusion head (FIG. 1) adapted to shape the hollow fibre. The shaped fibre is then cooled in the extrusion head to a temperature so that non-equilibrium liquid-liquid phase separation takes place to form a bi-continuous matrix of the polymer and solvent in which the polymer and solvent form two intermingled separate phases of large interfacial surface area. Finally, the solvent is removed from the polymer.The extrusion head for forming the abovementioned polymeric, porous hollow fibre has an elongated body (17, 18) defining an axial passageway (11) for receiving a lumen-forming fluid (14) and a first annular passage (12) therearound for receiving the molten mixture (15) from which the hollow fibre (21) is formed. A second annular passageway (13) is radially outward of the first annular passageway (12) and receives a coating fluid (16). A third annular passageway (19) receives a cooling fluid and has means (20) for directing the cooling fluid towards the outer surface of the coating fluid (16). The porous polymeric material of the fibre produced by the abovementioned process has a lacey or filamentous structure consisting of a plurality of polymer strands connected together at spaced apart locations along each strand.

摘要： A method of making a porous polymeric material by heating a mixture of a thermoplastic polymer and a cationic or non-ionic surfactant having a hydrophilic-lipophilic balance range of 4.0 to 6.0 to a temperature and for a time sufficient for the polymer and surfactant to mutually dissolve. The mixture is then cooled to a temperature so that non-equilibrium liquid-liquid phase separation takes place to form a bi-continuous matrix of the polymer and surfactant so that the polymer and surfactant form two intermingled separate phases of large interfacial surface area. The surfactant is then removed from the polymer. The porous polymeric material produced by the above method has a lacey or filamentous structure consisting of a plurality of polymer strands connected together at spaced apart locations along each strand.

摘要： A polyolefin microporous membrane is disclosed. The membrane has a width of not less than 100 mm, and a variation range of an F25 value in a width direction is not greater than 1 MPa. The F25 value is a value obtained by dividing a load at 25% elongation of a sample of the laminated polyolefin microporous membrane as measured with a tensile testing machine by a cross-sectional area of the sample.

摘要： A polymeric fiber for use in gas separation is formed from a spin dope which includes solvent and non-solvent materials. The fiber is passed through a quench bath, and then a leach bath, in which the solvent and non-solvent are removed. The quench bath and the leach bath include sets of rollers which transport the fiber through the system. Each set of rollers in the leach bath operates at a speed which is greater than or equal to the speed of the rollers which are immediately upstream. Thus, the fiber is stretched, in different amounts, at the same time that the solvent and non-solvent are being removed, and while the fiber is still wet. The resulting fiber has been found to exhibit superior flux and selectivity properties.
