| titleOfInvention | Method for producing polyvinyl acetal porous material |
| abstract | [PROBLEMS] To prevent clogging of pores, to ensure a sufficient amount of water permeability at a relatively low pressure, to have excellent thermal stability and chemical resistance of a film, to have sufficient strength, and to be fine particles such as bacteria. A method for producing a polyvinyl acetal porous material that can also be removed. The production method of the present invention includes a first polyvinyl acetal resin and a second polyvinyl acetal resin in which an acetalizing agent different from the acetalizing agent used in the first polyvinyl acetal resin is used. A step of heating a mixture containing a resin and a solvent to obtain a uniform polymer solution, a step of forming the polymer solution into a predetermined shape to obtain a molded product, and cooling the molded product for phase separation. And a step of extracting and removing the solvent present in the phase-separated molded product using an extractant capable of dissolving the solvent. [Selection figure] None |
