PRODUCTION OF CROSSLINKED POLYARYLENE SULFIDE

摘要

PURPOSE:To produce a powdery crosslinked polyarylene sulfide excellent in production efficiency in high yield. CONSTITUTION:A powdery uncrosslinked polyarylene sulfide is compression molded and granulated. The resultant granulated material in which >=50wt.% thereof preferably have >=0.7mm grain diameter and >=0.4g/cm<3> bulk density is then oxidatively crosslinked.
