An electrically conductive thermoplastic composition is prepared by melt blending a polymer and a masterbatch of carbon nanotubes in wax having a melting point of about 45 to about 150&#xb0; C. The masterbatch of carbon nanotubes in wax is more easily prepared than a conventional carbon nanotube masterbatch in high molecular weight polymer. Use of the masterbatch of carbon nanotubes in wax also improves the melt flow properties of the electrically conductive thermoplastic composition.

Carbon nanotube masterbatch, preparation thereof, and use in forming electrically conductive thermoplastic composition

A method of incorporating an additive into a polyamide-poly(arylene ether) composition includes the step of melt blending a polyamide, a poly(arylene ether), and a dispersion comprising a liquid carrier, an unmodified clay, and an additive. Using the dispersion rather than a polymer-based additive masterbatch saves energy. Like a polymer-based masterbatch, the dispersion provides the additive in a diluted form and therefore preserves the masterbatch's advantages of providing more uniform distribution additive in the plastic and avoiding direct handling of additives in the final compounding step.

Method of incorporating an additive into a polyamide-poly(arylene ether) composition, composition prepared thereby, and article comprising the composition

A composition comprises a poly(arylene ether), a polyamide, electrically conductive filler, an impact modifier, and wollastonite wherein the wollastonite particles have an average length to diameter ratio less than or equal to 5 and a median particle size of 2 to 5 micrometers. Methods of making the composition are also described.
