| titleOfInvention | Method for producing porous membrane |
| abstract | The present invention comprises a step of solidifying a film-forming solution containing a film material-forming polymer and an additive for controlling phase separation in a coagulation liquid to obtain a porous film precursor, and the remaining in the porous film precursor And a step of removing the additive for controlling the phase separation, wherein the ratio of the high molecular weight area in the integral molecular weight distribution curve is 11% as the additive for controlling the phase separation. It is related with the said manufacturing method using the polyvinyl pyrrolidone which is the following. According to the present invention, there is provided a method for producing a porous membrane that can remove an additive added to control phase separation in a short time and can produce a porous membrane having good permeability. Can do. |
