Abstract

PURPOSE: To obtain a resin in which the content of common salt is remarkably reduced without deteriorating its characteristics, by contacting a polyphenylene sulfide resin contg. common salt with a mixed solvent consisting of a polar aprotic solvent and ethylene glycol.
CONSTITUTION: A polyphenylene sulfide resin (PPS) contg. common salt is contacted with a mixed solvent consisting of a polar aprotic solvent and ethylene glycol. Commercially available PPS is produced by reacting p-dichlorobenzene with sodium disulfide in a polar solvent, and usually contains 1,000W3,000ppm (in terms of Na2O) of common salt. It is possible to reduce the content of common salt in the commercially available PPS to 10ppm or lower by the above method. It is preferred to bring PPS in a pulverized state into contact with the mixed solvent from the viewpoints of an operating efficiency. It is also preferred to use the heated mixed solvent.
