Abstract

The polymerization factors to meet the desired physical properties of polyacrylonitrile(PAN) spinning dope for on-line spinning were examined. The spinning dope was prepared by solution polymerization in dimethylsulfoxide solution induced by azobis-iso-butyronitrile. The physical properties of the spinning dope could be controlled by manipulating monomer concentration, initiator concentration and polymerization temperature. At the unusually high monomer concentrations, required in the on-line spinning process, the polymerization of PAN exhibited a little deviation from the theoretical prediction.
