A polyarylene sulfide containing reactive functional groups with a narrow dispersity and low amount of generated gas is produced by heating a cyclic polyarylene sulfide composition in the presence, with respect to 1 mole of arylene sulfide structural units, of 0.1 mole% to 25 mole% of a sulfide compound having reactive functional groups selected from amino groups, carboxyl groups, hydroxyl groups, acid anhydride groups, isocyanate groups, epoxy groups, silanol groups and alkoxysilane groups. |
