Abstract
A method for producing a porous material excelling in stability of preservation is produced. A method for the production of a porous material comprising a step for obtaining a porous polymer by polymerizing an HIPE containing a polymerizable monomer is disclosed, which method comprises a step for adding a compound capable of reacting with a polymerization initiator and/or a compound capable of reacting with an unsaturated double bond to said emulsion, said porous polymer and/or said porous material having a conversion of not less than 70%. According to this invention, it is made possible to produce a porous material excelling in stability in storage and to decrease the polymerization initiator and the residual monomer very simply.
