Abstract
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.
