PURPOSE:To produce a polyarylene sulfide ketone having a high melt stability and a high heat resistance in a short time at a high yield by reacting a specific dihalogenated aryl ketone with an alkali metal sulfide in the presence of a quinone. CONSTITUTION:1mol of a dihalogenated aryl ketone of the formula (wherein R1, R2, R3, and R4 are each a 1-12C alkyl group, an arom. group, an alicyclic group, or a hydrogen atom; and X is a halogen atom) is reacted with 0.95-1.05-mol (in terms of total sulfur content) of an alkali metal sulfide in the presence of a quinone. |
