| titleOfInvention | Polyarylene sulfide purification method and purification apparatus |
| abstract | PROBLEM TO BE SOLVED: To provide a method for purifying polyarylene sulfide from which high-quality polyarylene sulfide can be stably obtained, and an apparatus for purifying the same. SOLUTION: The polyarylene sulfide is washed with a cleaning solution, and the polymer phase 8 containing the polyarylene sulfide is washed. And a solution phase 9 containing a washing liquid, and the viscosity of the polymer phase 8 or the density difference between the polymer phase 8 and the solution phase 9 is measured to detect the liquid level 10 of the polymer phase 8 and to separate the polymer phase 8 A method for purifying a polyarylene sulfide, comprising removing the polyarylene sulfide. The difference between the viscosity of the polymer phase 8 or the density difference between the polymer phase 8 and the solution phase 9 is determined by the vibratory process viscometer 7 in which the liquid contact part 11 is made of stainless steel, Hastelloy alloy, Ti or Ti alloy, or the remote seal type. Since the measurement is performed by the differential pressure transmitter, the liquid level 10 of the polymer phase 8 can be accurately detected. |
