Abstract: An antistatic additive for polyamide compositions and articles is disclosed, which can be concisely defined as a "polyoxyalkylated aminoacid." This class of compounds is preferably prepared by placing the selected aminoacid in the presence of the selected oxyalkylene, in suspension in a liquid medium. The latter is preferably an organic solvent for the polyoxyalkylene, but is a nonsolvent for the aminoacid as such. The polyoxyalkylation is encouraged by the presence of an alkali metal salt of the aminoacid: the sodium salt is preferred. The compounds so prepared have an unpredictably high degree of emulgability towards the polyamides so that a completely satisfactory dispersion of the novel additives in the polyamides can be achieved. Examples of amino-acids are omega-aminododecanoic, omega-aminoundecanoic, epsilon-aminocapronic, (also known as epsilon-aminocaproic) sulphanilic, para-aminobenzoic, 2-aminoethanesulphonic and aminoacetic acids.
