Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a manufacturing method capable of providing polyarylene sulfide less in metal amount in short time by resolving defects of conventional catalyst technologies which require high temperature and long time and generate metal residue in polyarylene sulfide during a polymerization reaction of cyclic polyarylene sulfide to polyarylene sulfide.SOLUTION: A polyarylene sulfide prepolymer containing at least 50 wt.% or more of cyclic polyarylene sulfide represented by the formula (A) and having repeating number in the formula of m=4 to 50 is heated in presence of an arylene sulfide compound having a terminal SH group of 0.001 to 20 mol% to a sulfur atom in the polyarylene sulfide prepolymer. Ar represents an arylene group.SELECTED DRAWING: None 【課題】環式ポリアリーレンスルフィドのポリアリーレンスルフィドへの重合反応に際し、高温、長時間を要し、ポリアリーレンスルフィド中に金属残留を生じる従来の触媒技術の欠点を解決し、金属量の少ないポリアリーレンスルフィドを短時間で得ることのできる製造方法を提供することを課題とする。【解決手段】式（Ａ）で表され、かつ式中の繰り返し数ｍ＝４〜５０である環式ポリアリーレンスルフィドを少なくとも５０重量％以上含むポリアリーレンスルフィドプレポリマーを、ポリアリーレンスルフィドプレポリマー中の硫黄原子に対し０．００１〜２０モル％の、末端ＳＨ基を有するアリーレンスルフィド化合物の存在下で加熱する。（Ａｒはアリーレン基を表す。）【選択図】なし
