Abstract
This invention has for an object thereof the provision of a method for the production of a porous cross-linked polymer which can freely control the upper and lower surface behavior of the porous cross-linked polymer, the width and the thickness of the polymer and can perform continuously a process ranting from a step of supplying the emulsion through a step of polymerizing it.The object of this invention, in the production of a porous cross-linked polymer by polymerizing a water-in-oil type high internal phase emulsion, is accomplished by a method for the production of a porous cross-linked polymer characterized by performing continuously a process ranting from a step of supplying the emulsion through a step of polymerizing it while having the outer surface part of the emulsion retain an atmosphere or a state having a lower oxygen content than the ambient air.
