Abstract:
Disclosed are a branched poly(arylene sulfide) resin having a melt viscosity measured at a temperature of 310° C. and a shear rate of 1200 sec−1 of 65 to 450 Pa·s, a maximum draft ratio of 6500 or more, and a degree of whiteness of 65 or more; moreover, a branched poly(arylene sulfide) resin preferably having a dependence of melt viscosity on shear rate of 1.4 to 2.6 or a melt stability of 0.85 to 1.30; and a method for producing a branched poly(arylene sulfide) resin, wherein a sulfur source and a dihaloaromatic compound are caused to undergo a polymerization reaction at a temperature of 170 to 290° C. in the organic amide solvent in the presence of a polyhaloaromatic compound in an amount of 0.0001 to 0.01 mol per mol of the fed sulfur source.
