    摘要: The invention relates to a method for removing a process solvent (P-sol) from a polymer extrudate, especially in connection with a process for producing a microporous membrane. The method involves contacting the extrudate with chlorinated hydrocarbon (CHC) and hydrofluoroether (HFE) in a first stage; contacting the extrudate from the first stage with HFE in a second stage; combining the first and second waste streams and then separating the P-sol from the combined streams to make an HFE-CHC stream; cooling the HFE-CHC stream to make an HFE-rich phase and a CHC-rich phase; and conducting the CHC-rich phase and/or the HFE-rich phase to step (A).

    摘要: A method of producing a microporous thermoplastic resin membrane of excellent permeability having uniform and fine micropores without filling stress concentrators to the thermoplastic resin is provided. Namely, there is provided a method of producing a microporous thermoplastic resin membrane, in which a thermoplastic resin foam incorporating fine cells having a ratio B/A between a cell size (A) and a wall thickness (B) of the cells of less than 0.5 and having a void ratio of not less than about 50% is subjected to plastic deformation of the boundaries of the cells themselves sufficient to cause shape deformation of the cells, thereby breaking the boundaries of the cells. Also there is provided a microporous thermoplastic resin membrane of excellent permeability having uniform and fine micropores produced by the method as described above.
