Title:
METHOD FOR MANUFACTURING POLYARYLENE SULFIDE RESIN
Document Type and Number:
WIPO Patent Application WO/2010/058713
Kind Code:
A1
Abstract:
Disclosed is a method for manufacturing a polyarylene sulfide resin by causing a reaction with a polyhalo aromatic compound (a), an alkali metal hydrosulfide (b), and an organic acid alkali metal salt (c) in the presence of a solid alkali metal sulfide and an aprotic polar organic solvent. This method for manufacturing a polyarylene sulfide resin is characterized in that the reaction is caused with the organic acid alkali metal salt (c) being used in a ratio of at least 0.01 mol and less than 0.9 mol with respect to a total of one mole of the solid alkali metal sulfide and the alkali metal hydrosulfide (b), and with the amount of moisture exiting in the reaction system being 0.02 mol or less with respect to one mole of the aprotic polar organic solvent. This method for manufacturing a polyarylene sulfide resin has high productivity on an industrial scale, and the obtained polyarylene sulfide resin can have a remarkably high molecular weight.
