Abstract: Using H2S, NaOH and p-C6H4Cl2 as raw materials and proper Na3PO4 as an assistant in hex-amethylphosphoryltriamide(HPT), the crystal linear poly (p-phenylene sulfide) resins with high molecular weight (HMWPPS) was synthesized during 4~5 h under normal pressure.The properties of the polymer were determined, m. p. >290 ℃; decomposition temperature by heat>500 ℃; low shear viscosity at melting state: 3.0-68.0×103 Pa (determined at 303 ℃). The product was used to do the melt spun test directly and the fiber of the HMWPPS was obtained. This method has following obvious advantages as the equipment is simple, operation is easy, reaction system has a higher activity, solvent is stable, product recovery ratio is high, cost is low and it is easy to put into large-scale production.
