  • Antistatic polyamide compositions which are stabilized against yellowing
    Patent number: 3962176
    Abstract: This invention relates to antistatic compositions of high molecular weight linear aliphatic polyamides which are stabilized against yellowing due to the action of heat. These polyamides which may be formed into films or fibers, are prepared by the solvent-free condensation of salts of aliphatic diamines with aliphatic dicarboxylic acids and/or lactams and contain homogeneously distributed therein a composition of one or more polyoxyalkylene compounds and tertiary amides or diamides, having at least one tertiary amide group.
