Thermoplastic compositions are provided which have electrostatic dissipative properties. The thermoplastic composition is prepared by combining at least the following initial ingredients: (i) a thermoplastic polyurethane, which is prepared by reacting a polyalkylene glycol, a diisocyanate and a chain extender having at least two hydroxyl groups; (ii) a thermoplastic polyester, wherein the polyester is a polylactone; and (iii) a quaternary ammonium compound. The composition may additionally include an organic polymer to which is imbued electrostatic dissipative properties as a result of incorporating the three initial ingredients.
L'invention concerne des compositions thermoplastiques ayant des propriétés de dissipation électrostatique. On prépare ladite composition en combinant au moins les ingrédients initial suivants: (i) un polyuréthane thermoplastique, que l'on prépare en faisant réagir un polyalkylène glycol, un di-isocyanate et un allongeur de chaîne comportant au moins deux groupes hydroxyles, (ii) un polyester thermoplastique, qui est un polylactone, et (iii) un composé ammonium quaternaire. La composition peut en outre comprendre un polymère organique qui acquiert des propriétés de dissipation électrostatique de par l'incorporation des trois ingrédients initiaux.
