Abstract: The present invention relates to a method of preparing a polyphenylene sulfide and a high-viscosity polyphenylene sulfide prepared using the method. In this method, the ratio of an organic phase to an aqueous phase is controlled by controlling dehydration conditions, so that high viscosity may be realized without adversely affecting a reaction or physical properties during preparation of the polyphenylene sulfide.
