Abstract
Embodiments of the present invention relate to polyarylene sulfide that may exhibit excellent processability at low temperature, decrease outgassing and flash or burr generation, and thus may satisfactorily mold a product requiring high molding accuracy, and a method for preparing the same. Specifically, the polyarylene sulfide includes an arylene sulfide repeat unit and an arylene disulfide repeat unit, wherein the weight ratio of the arylene sulfide repeat unit:arylene disulfide repeat unit is 1:0.0001 to 1:0.05.
