| titleOfInvention | Method for producing polyarylene sulfide |
| abstract | (57) 【Abstract】 PROBLEM TO BE SOLVED: It is possible to reduce the production cost by eliminating the complexity of the process and the increase in the equipment cost due to the multi-stage cleaning tank, and to efficiently recover the lithium salt to obtain the product P. Provided is an efficient method for producing polyarylene sulfide capable of increasing the purity of AS. SOLUTION: N-methyl-2-pyrrolidone (NMP) Lithium hydroxide, hydrogen sulfide, and paradichlorobenzene (PDCB) are preliminarily polymerized as polymerization components, and water is added to the obtained polymerization solution (I) to separate a polymer concentrated phase and a solvent phase, Then, a solvent (NMP and water) is added to the separated polymer-rich phase for main polymerization. |
