Abstract
The present disclosure relates generally to a process for producing polymer fibers, typically polyacrylonitrile-based fibers, the morphology of which is controlled by the use of a polymer additive to form a polymer blend with polyacrylonitrile, which is then subjected to certain coagulation and washing conditions. The present disclosure also relates to carbon fibers produced by processing the polymer fibers made.
