  • Antistatic polyphenylene ether compositions
    Patent number: 4123475
    Abstract: Thermoplastic compositions comprising a polyphenylene ether resin alone or in admixture with a styrene resin are rendered resistant to the accumulation of surface electrostatic charges by the inclusion, in a minor, effective amount, of an antistatic agent consisting of a mixture of triethanolamine, toluene sulfonic acid and sodium lauryl sulfate. Flame retardant embodiments are also provided.
