Abstract:
1. A polyarylene sulfide that is prepared from a composition comprising 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; wherein the sulfur-containing polymerization terminator is at least one selected from the group consisting of benzothiazolesulfenamide and dithiocarbamate; the benzothiazolesulfenamide being at least one selected from the group consisting of N-cyclohexylbenzothiazole-2-sulfenamide, 2-morpholinothiobenzothiazole, and N—N-dicyclohexylbenzothiazole-2-sulfenamide; and the dithiocarbamate being at least one selected from the group consisting of zinc dimethyldithiocarbamate and zinc diethyldithiocarbamate.
