A new process for preparing poly (phenylene sulfide amide, PPSA), which is by reaction of sulfur instead of sodium sulfide as S source with dichloro- benzamide (DCBA) and alkali in polar organic solvent at the atmospheric pressure (called sulfur solution route), is reported in the present paper. The influences of polymerization time, molar ratio of precursors, catalyst and solvent upon the polymer were investigated.
