ABSTRACT:
A thermoplastic polyurethane is provided which has electrostatic dissipative properties. The thermoplastic polyurethane comprises the polymeric reaction product of an ethylene ether oligomer glycol intermediate co-reacted with a non-hindered diisocyanate and an extender glycol to produce the polyurethane polymer. The ethylene ether oligomer glycol intermediate comprises a polyethylene glycol. The oligomer glycol intermediate has an average molecular weight from about 500 to about 5,000.
