Abstract

Poly(arylene sulfide) resins are modified by melt mixing a resin with a basic additive to form a resin product composition. The basic additive is selected from the group consisting of inorganic hydroxides, inorganic oxides and organic metal salts wherein the metals are from Group IA, IIA, or IIB and the salts are of carboxylic acids and phenols. The product compositions are suitable for injection molding, film forming and fiber spinning processes.
