Abstract:
1. Polyarylene sulfide that is in the form of a pellet of 2 to 10 mm size immediately after polymerization, and has residual solvent content of 300 ppm or less, based on the total weight of the resin; wherein the polyarylene sulfide is produced by a method comprising polymerizing a diiodide aromatic compound and an initial amount of a sulfur compound; adding an additional amount of sulfur compound at a point after the addition of the initial amount of a sulfur compound; and drying the resulting polyarylene sulfide at 120 to 160° C. for 1 to 2 hours to give polyarylene sulfide in the form of a pellet of 2 to 10 mm size immediately after polymerization, and has residual solvent content of 300 ppm or less, based on the total weight of the resin.
