    Abstract: Inclusion of relatively small amounts of organic ionic species, such as calcium stearate, in the preparation of an electrically conductive polymer composite composition provides a composition having enhanced electrical properties relative to the composite composition lacking the added organic ionic species. As a result of this enhancement, normally insulating materials which rely upon a conductive filler to render them electrically conductive, can be made to achieve a given level of conductivity using less of the conductive filler than would otherwise be required. As a result, the adverse effects of the conductive filler on the polymer's physical properties can be minimized while maintaining a high level of electrical conductivity.

    Abstract: A flame retardant polyamide fiber is prepared from a composition containing specific amounts of a polyamide, a poly(phenylene ether), a flame retardant that includes a metal dialkylphosphinate, and a compatibilizing agent. The composition used to form the fiber can be prepared in a process that includes melt blending a portion of the polyamide with all the other ingredients to form an intermediate composition, and then melt blending the intermediate composition with the remainder of the polyamide. The composition has small disperse phase particles that facilitate its use to melt spin fibers.

    Abstract: A piston guide ring for use in a piston-cylinder assembly includes a compatibilized polyamide-poly(arylene ether) blend. The compatibilized polyamide-poly(arylene ether) blend includes about 35 to about 95 parts by weight polyamide and about 5 to about 65 parts by weight poly(arylene ether), based on 100 parts by weight total of the polyamide and the poly(arylene ether). The piston guide rings provide improved compressive strength at elevated operating temperatures, more isotropic mold shrinkage, and reduced moisture absorption compared to piston guide rings prepared from polyamide.
