PROBLEM TO BE SOLVED: To provide inherently electrostatic dissipative polymers.SOLUTION: The present invention relates to inherently electrostatic dissipative polymers, such as thermoplastic urethane (TPU), and compositions thereof. The present invention provides a composition comprising (a) an inherently dissipative polymer and (b) a halogen-free metal salt of an amidoalkanesulfonic acid, a hydrocarbyl-substituted benzenesulfonic acid, or a mixture thereof, or a halogen-free metal salt of a polymer derived therefrom. The invention also provides a shaped polymeric article comprising the inherently dissipative polymer compositions described herein. The invention also provides a process of making the inherently dissipative polymer compositions described herein. The process includes the step of mixing the halogen-free metal-containing salt into the inherently dissipative polymer.SELECTED DRAWING: None |
