titleOfInvention | Method for producing polyphenylene sulfide |
abstract | (57) [Summary] [Object] To provide a method for producing a polyphenylene sulfide having a high molecular weight under mild conditions and producing a small amount of oligomer by-products. [Structure] Alkali metal salt of dithiol (I) and p-dibromobenzene (II) in polar organic solvent (I) / (II) = 0.85 to 1.15, the polymerization system monomer concentration of p-dibromobenzene (II) is 0.3 mol / l or more, Using a die having a length / diameter of 2 / 0.5 (mm / mm), which is characterized by being polymerized at a temperature of 120 to 280 ° C. 30 A method for producing a polyphenylene sulfide, which has a melt viscosity of 600 poise or more measured at 0 ° C. and 200 (sec) −1 . |
