ABSTRACT:
Porous fibers which are much preferred for having various functionalities such as ion exchangeability, catalytic activity, etc. can be produced by impregnating a mixed monomer liquid of at least one monovinyl monomer and at least one polyvinyl monomer which contains a polymerization initiator in substrate fibers capable of being swollen by 30 - 500 volume % with the mixed monomer liquid, polymerizing the monomers in the state of being absorbed in the fibers and then removing said substrate fibers.
