Abstract: A process for producing a hollow carbon or ion-exchange filament which comprises treating a filament consisting of a fiber-forming polymer of predominantly an uncured novolak resin composition with a curing reagent in the presence of a curing catalyst to effect the cure of the filament extending from the peripheral portion to the axial portion thereof to a depth of 20-90% of the cross-sectional area of the filament, removing the uncured core portion of the filament by extraction with a solvent, and then subjecting the resulting hollow novolak resin filament to a carbonization treatment or introducing an ion-exchangeable group into the resulting hollow novolak resin filament; and products produced by this process.
