Claim 1

Independent Claim 197 words

A process for producing a polyarylenesulfide complex having the properties as defined in (A) through (C) below, which comprises reacting a polyarylenesulfide with 0.05 to 20 miles of at least one strongly basic metal compound selected from the group consisting of a hydroxide of an alkaline earth metal, an oxide of an alkaline earth metal and a hydrocarbyloxide of an alkali metal per 100 mols of arylenesulfide groups contained in the polyarylenesulfide said reaction being conducted with the polyarylenesulfide in the molten state at a temperature from its melting point to 400° C. and in the substantial absence of a liquid dispersant: (A) η*/η o *=3 to 100, wherein the η* and η o * stand for melt viscosities of the complex and the starting polyarylenesulfide, respectively; (B) ΔT c2 =(T c2 ) 0 -T c2 =10° to 100° C., wherein T c2 and (T c2 ) 0 stand for crystallization temperatures of the complex and the starting polyarylenesulfide, respectively, observed when the polyarylenesulfide is cooled from its molten state; and (C) Δ(ΔE)-ΔE-(ΔE) 0 =5 to 75 kcal/mol, wherein ΔE and (ΔE) 0 stand for apparant flow activation energies of the complex and the starting polyarylenesulfide, respectively.

Claim 4

Dependent Claim 205 words
