    • The present invention relates to a process of producing polyarylene sulfide (PAS) and PAS resin produced therefrom, and more specifically, to a process of preparing polyarylene sulfide with better thermal properties and luminosity than conventional PAS and the PAS resin produced therefrom, including the steps of: a) melting and mixing a composition including solid sulfur, iodinated aryl compounds, and a polymerization terminator; b) polymerizing the molten mixture of step a) for 1 to 30 hours while increasing the temperature and decreasing the pressure from initial reaction conditions of a temperature of 180 to 250° C. and a pressure of 50 to 450 Torr to final reaction conditions of a temperature of 270 to 350° C. and a pressure of 0.001 to 20 Torr; and c) heating the reaction product of step b) at a temperature of 270 to 350° C. for 1 to 25 hours. The process of polyarylene sulfide resin further includes a step of heating the polymerized product at a high temperature following the polymerization step, and uses the polymerization terminator in a suitable amount to control the molecular weight of polyarylene sulfide, thereby producing polyarylene sulfide with excellent thermal properties and luminosity.
