Process for producing porous polymer |
摘要 |
A method of production is provided which is capable of efficiently producing in a very short period of time a porous polymer possessing a uniform foam structure and truly excelling in absorption properties and physical properties. It is a method for the production of a porous polymer, characterized by comprising (a) an emulsifying step for forming a water-in-oil type high internal phase emulsion (HIPE) by mixing and stirring an oil phase containing a polymerizing monomer component and a surfactant as essential components, (b) a shaping step for shaping the HIPE in a specific form, and (c) a polymerizing step for polymerizing the shaped HIPE and controlling the temperatures of the emulsion at the component steps (a)-(c) so that they may not produce a change exceeding 10° C. or controlling all the component steps so that they may proceed at temperatures of not lower than 80° C.
