ELECTROSTATIC DISSIPATIVE TPU AND COMPOSITIONS THEREOF

摘要

The present invention relates to an electrostatic dissipative thermoplastic polyurethane composition made by reacting (a) at least one polyester polyol intermediate with (b) at least one diisocyanate and (c) at least one chain extender. The polyester polyol intermediate, may be derived from at least one dialkylene glycol and at least one dicarboxylic acid, or an ester or anhydride thereof. The invention further provides for methods of making said thermoplastic polyurethane composition, polymer blends containing said thermoplastic and polymer articles made from said thermoplastic.
