Abstract
Embodiments of the present invention relate to recyclable polyarylene sulfide that may exhibit and maintain excellent mechanical properties, particularly does not exhibit decrease in melt viscosity when it is molten, and thus, exhibit little deterioration of mechanical properties, and a method for preparing the same. The polyarylene sulfide has initial melt viscosity measured at 300° C. of 300 to 6000 poise, and melt viscosity after heat treated and molten at 300° C., equal to or greater than the initial melt viscosity.
