| Zusammenfassung: | A novel method for producing an olefinic resin porous material with no skin layer is provided. The method for producing an olefinic resin porous material disclosed herein includes the steps of preparing a single phase in which an olefinic resin, a hydrocarbon compound, and a polar compound are mixed one another, in a pressure-resistant container, introducing high pressure carbon dioxide into the pressure-resistant container, and releasing the pressure in the pressure-resistant container. The polar compound has a hydroxy group or a carbonyl group. Introducing the high pressure carbon dioxide is carried out such that the pressure in the pressure-resistant container reaches 6 MPa or higher. |
