Abstract
The present invention relates to polyarylene sulfide, in which a ratio of a peak area of a polymer chain of a second polyarylene sulfide having a lower molecular weight than the maximum peak molecular weight to a peak area of a polymer chain of a first polyarylene sulfide having a higher molecular weight than the maximum peak molecular weight is 1.3 or less in the molecular weight distribution of the polyarylene sulfide, as measured by gel permeation chromatography using polystyrene as a standard, and a preparation method thereof. This polyarylene sulfide exhibits excellent processability and generates no burrs (flashes) or the like, and can satisfactorily mold a product requiring high molding precision.
