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.

Abstract: This invention relates to a method of preparing poly(arylene sulfide) (PAS) from an iodo compound and a sulfur compound, and more particularly, to a method of preparing PAS, including adding a sulfur-containing polymerization terminator when PAS is produced using an iodo compound as an intermediate. Thereby, in final PAS, the residual iodine content may be maintained at the same level or decreased and other properties may be maintained at equal or superior levels, thanks to the use of the sulfur-containing polymerization terminator, which is much lower in price than conventional polymerization terminators.
