摘要：
A method for preparing polyarylene sulfide having reduced iodine content and excellent thermal stability is described. The method includes reacting a composition comprising diiodide aromatic compounds, sulfur compounds, and a polymerization terminator. The preparation method may effectively reduce iodine content of polyarylene sulfide to prevent corrosion of post processing equipment, improve properties of polyarylene sulfide such as thermal stability, and the like, and thus, it may be usefully applied in the industrial field relating to preparation of polyarylene sulfide.
