<p>A branched poly(arylene sulfide) resin having a melt viscosity of 10.0 x 10 4 to 40.0 x 10 4 Pa·s as measured at a temperature of 330°C and a shear rate of 2 sec -1 , an average particle diameter of 50 to 2,000 µm, and a melt viscoelasticity tan ´ of 0.10 to 0.30 as measured at a temperature of 310°C and an angular velocity of 1 rad/sec; a process for producing the resin, which including subjecting a sulfur source and a dihalo-aromatic compound to a polymerization reaction in an organic amide solvent, adding a polyhalo-aromatic compound and a phase separation agent to the polymerization reaction mixture at the point of time the conversion of the dihalo-aromatic compound has reached at least 80%, and then heating the polymerization reaction mixture to continue the polymerization reaction; and use of the resin as a polymeric modifier.</p> |
