A thermoplastic polyether polyurethane having high moisture vapor transmission, high melting point and static dissipative properties is disclosed. The thermoplastic polyether polyurethane is prepared by reacting a hydroxyl terminated polyether intermediate, an aromatic chain extender glycol, and a polyisocyanate. The weight proportions of the reactants used to make the TPU satisfy the equation of ( a ) = wt . of hydroxyl terminated polyether intermediate wt . of polyisocyanate + wt . of aromatic chain extender = 1.6 ± 0.4 The polymers formed are useful for melt-spun fibers, fabric coatings for breathable garments, house wrap, roofing membranes, and other applications requiring high vapor transmission and high melting points.
