Abstract
This invention is targeted at providing a method for producing a porous cross-linked polymer material excelling in absorption properties and mechanical strength in a short period of time. In the production of a porous cross-linked polymer material from an HIPE, the method of this invention is characterized by comprising a step of polymerizing the HIPE till the bromine value thereof falls to not more than 25% of the value existing prior to the polymerization and a subsequent step of after curing the porous cross-linked polymer material by means of an active energy ray or a temperature higher than the polymerization temperature.
