[0002] Polyphenylene sulfide is a new type of high-performance thermoplastic resin with excellent heat resistance, chemical corrosion resistance, flame retardancy, and insulation. It has relatively high hardness and strength, excellent mechanical properties, and can be molded by a variety of processing methods. It has been widely used in automotive parts, electronic devices, petrochemical industries, etc. There are two common production methods for polyphenylene sulfide, one is the sodium sulfide method, and the other is the sulfur solution method. The sodium sulfide method prepares polyphenylene sulfide using aqueous sodium sulfide and p-dichlorobenzene as raw materials, N-methylpyrrolidone as solvent, and lithium chloride as the main auxiliary agent. Polyphenylene sulfide is synthesized at high temperature and high pressure, specifically including dehydration, synthesis, filtration, desalting and drying processes.
