Abstract
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): PA0 (A) .eta.*/.eta..sub.0 *=3 to 100, wherein the .eta.* and .eta..sub.0 * stand for melt viscosities of the complex and the starting polyarylenesulfide, respectively; PA0 (B) .DELTA.T.sub.c2 =(T.sub.c2).sub.0 -T.sub.c2 =10 to 100.degree. C., wherein T.sub.c2 and (T.sub.c2).sub.0 stand for crystallization temperaturs of the complex and the starting polyarylenesulfide, respectively, observed when the polyarylenesulfide is cooled from its moten state; and PA0 (C) .DELTA.(.DELTA.E)=.DELTA.E-(.DELTA.E).sub.0 =5 to 75 kcal/mol, wherein .DELTA.E and (.DELTA.E).sub.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.
