CA 2083138
Polyolefin foams and films having improved electrostatic properties are provided by incorporating into the polyolefin foam or film a novel antistatic additive composition comprising 0.1 to 10 parts per hundred based on the weight of the olefin polymer of a quaternary ammonium salt and 0.1 to 10 parts per hundred based on the weight of the olefin polymer of a partial ester of a long-chain fatty acid with a polyol. A method of making the foam containing the novel antistatic additive composition is also disclosed.
L'invention est une méthode servant à améliorer les propriétés électrostatiques des mousses et des films à polyoléfine en introduisant dans ces mousses ou ces films un nouvel additif antistatistique de 0,1 à 10 % en poids de la polymère d'oléfine d'un sel d'ammonium quaternaire et de 0,1 à 10 % en poids de la polymère d'oléfine d'un ester partiel d'un acide gras à longue chaîne avec un polyol. Une méthode de fabrication de mousses contenant ce nouvel additif antistatique est également révélée.
