Novel polyarylenesulfide complexes are obtained by reacting a polyarylenesulfide with 0.05 to 20 mols of at least one strongly basic metal compound per 100 mols of arylenesulfide groups contained in the polyarylenesulfide under a uniformly dispersed condition, and have the properties defined in the following (A) through (C): (A) eta */ eta 0*=3 to 100, wherein the eta * and eta 0* stand for melt viscosities of the complex and the starting polyarylenesulfide, respectively; (B) DELTA Tc2=(Tc2)0-Tc2=10 to 100 DEG C., wherein Tc2 and (Tc2)0 stand for crystallization temperaturs of the complex and the starting polyarylenesulfide, respectively, observed when the polyarylenesulfide is cooled from its moten state; and (C) DELTA ( DELTA E)= DELTA E-( DELTA E)0=5 to 75 kcal/mol, wherein DELTA E and ( DELTA E)0 stand for apparent flow activation energies of the complex and the starting polyarylenesulfide, respectively. The polyarylenesulfide complexes have higher melt viscosity with improved flow characteristics. |
