    • A method of reducing friction losses in aqueous and nonaqueous liquids is disclosed. A certain polymeric material has heretofore been admixed to this end with flowing liquids, such polymer being dissolvable to form a solution. The prior art method is effective for friction loss reduction, but has a drawback in that the polymer is susceptible to scission of its chains under shear stress and hence is unstable in the solution. The invention disclosed is based on the discovery that friction losses in liquids can be reduced with maximum stability by adding to a liquid a predetermined amount of selected organo-polymeric microfibrils which are insoluble but highly dispersible in the liquid. The method of the invention may be applied for instance in the transport of various liquids and crude oils through pipelines and also in the circulation of aqueous and nonaqueous lubricants.

    • A process for preparing permeable membranes which comprises mixing in the molten state two different kinds of thermoplastic synthetic resins which are partly compatible with each other, shaping the molten mixture into a sheet- or film-like melt, passing the film- or sheet-like melt through a heated zone, cooling and solidifying it, the time from the shaping of the molten mixture into the film- or sheet-like melt to its cooling and solidification (melt maintenance time) being adjusted to 10 to 600 seconds, treating the resulting film or sheet with a solvent which is a good solvent for one of the component resins but is a poor solvent for the other to dissolve and remove the soluble resin, and drying the product. In place of the resin to be removed by the solvent, rubbers or oligomers having partial compatibility with the resin which remains undissolved can be used.
