An antistatic composition comprises (a) at least one ionic salt consisting of a nonpolymeric nitrogen onium cation and a weakly coordinating fluoroorganic anion, the conjugate acid of the anion being a superacid; and (b) at leat one thermoplastic polymer. The composition exhibits good antistatic performance over a wide range of humidity levels.
L'invention concerne une composition antistatique comprenant (a) au moins un sel ionique composé d'un cation onium d'azote non polymère, et d'un anion fluoro-organique faiblement coordonnant, l'acide conjugué de l'anion étant un superacide, et (b) au moins un polymère thermoplastique. Cette composition présente un fort pouvoir antistatique sur une grande gamme de taux hygrométriques.
