Abstract
PURPOSE: To eliminate or rationalize the drying process of acrylonitrile polymer by mechanical removal of water contained in a swollen acrylonitrile polymer polymerized in an aqueous medium to its content less than 60% and then by adding the solvent to the resulting polymer to dissolve it into the dope solution.
