Abstract
The present invention relates to a polyarylene sulfide that is prepared from a composition including 100 parts by weight of solid sulfur, 500 to 10,000 parts by weight of iodinated aryl compounds, and 0.03 to 30 parts by weight of a sulfur-containing polymerization terminator with respect to 100 parts by weight of the solid sulfur, and has a melting temperature (Tm) of 255 to 285° C., and luminosity of 40 or higher as defined by the CIE Lab color model, and a process of preparing the same. The PAS resin is prepared from a composition including a sulfur-containing polymerization terminator and thus has excellent thermal properties and luminosity.
