Abstract: The present disclosure relates to a process for producing one or more carbon fiber precursor fibers, particularly by spinning a polymer solution, wherein the polymer has a polydispersity (PDI) of less than or equal to 2, in a coagulation bath with a jet stretch of about 5 to about 60. The one or more carbon fiber precursor fibers produced may be used for producing carbon fiber, typically carbon fiber used in manufacturing composite materials.
