Abstract
A reactive functional group-containing polyarylene sulfide being narrow in dispersity and little in gas generation amount is produced by heating a cyclic polyarylene sulfide composition in the presence of 0.1 mol % to 25 mol %, per mol of arylene sulfide structural units, of a sulfide compound having a reactive functional group selected from among an amino group, a carboxyl group, a hydroxyl group, an acid anhydride group, an isocyanate group, an epoxy group, a silanol group, and an alkoxysilane group.

A method of producing a polyarylene sulfide (c) comprising heating a cyclic polyarylene sulfide composition (a) in the presence of 0.1 mol % to 25 mol %, per mol of arylene sulfide structural units, of a sulfide compound (b) having a reactive functional group represented by formula (A):
- wherein at least one of Y and X is a functional group selected from the group consisting of an amino group, a carboxyl group, a hydroxyl group, an acid anhydride group, an isocyanate group, an epoxy group, a silanol group, and an alkoxysilane group, and n represents an integer of 0 to 20.
