The disclosure uses a sulfur-containing compound and a halogenated aromatic compound as raw materials, an alkaline compound and a fatty acid as polycondensation aids to carry out a polycondensation reaction. After purification treatment, aprimarypolyphenylene sulfide is obtained. Then, the primary polyphenylene sulfide reacts with a chain extender at a high temperature to form a high molecular weight polyphenylene sulfide resin.The preparation method of the disclosure has the advantages of high yield, low cost, and is capable of selectively and controllably preparing polyphenylene sulfide resins with different melt viscosities and molecular weights, and the obtained polyphenylene sulfide resins have excellent heat resistance.The linear high molecular weight polyphenylene sulfide resin with high thermal stability obtained by the disclosure can be used for producing plates, pipes and rods, can be mechanically processed like metals, such as cutting, grinding, polishing, drilling,and can be used to produce fibers, membranes, films, and especially are applicable toautomotive parts, electronic/electrical equipment, chemical and machinery industry.
