Antistatic polymer composition comprising a thermoplastic polymer and a copolymer with polyamide blocks and polyether blocks based on ethylene oxide. Antistatic polymer composition comprises: (a) a thermoplastic polymer (A); and (b) a copolymer (B) with polyamide blocks and polyether blocks consisting essentially of ethylene oxide units -(C2H4O)-, the copolymer (B) having a fusion temperature of 80-150 (90-135) degrees C. La présente invention concerne une composition de polymères antistatiques et plus précisément une composition comprenant un polymère thermoplastique (A) et un copolymère (B) à blocs polyamides et blocs polyéthers comprenant essentiellement des motifs oxyde d'éthylène -(C2H4-O)- le copolymère (B) ayant une température de fusion comprise entre 80 et 150°C. Elle est utile pour les polymères (A) qui sont thermosensibles ou qui se transforment à basse température.
