ABSTRACT:
Blends of poly(arylene sulfide)s, liquid crystalline polyesters and liquid crystalline poly(esteramide)s exhibit a lower melt viscosity than would be expected based on the melt viscosities of analogous blends of liquid crystalline polyesters and poly(arylene sulfide)s that have the same overall amount of liquid crystalline polymer. The viscosities are reduced over a wide range of compositions. Such blends are useful in the manufacture of electronic components, particularly connectors.
