Method for producing cyclic polyarylene sulfide |
| abstract |
There is provided a production method of a cyclic polyarylene sulfide from a reaction mixture including at least a sulfidizing agent (a), a dihalogenated aromatic compound (b) and an organic polar solvent (c). The production method includes: a process 1 of heating the reaction mixture having an arylene unit of not less than 0.80 mol but less than 1.05 mol per 1 mol of the sulfur content in the reaction mixture; and subsequent to the process 1, a process 2 of further causing the reaction to proceed after addition of the dihalogenated aromatic compound (b) to have the arylene unit of not less than 1.05 mol and not greater than 1.50 mol per 1 mol of the sulfur content in the reaction mixture. |
