ABSTRACT OF THE DISCLOSURE Thermoplastic polyether polyurethane elastomers are provided by reacting and forming: (a) a novel liquid polyurethane quasi-prepolymer having a free NCO content of from about 16 percent to about 25 percent; (b) a reactive poly(oxypropylene-oxyethylene) diol; and (c) as an extender, a short chain diol in the presence of (d) a catalyst. The elastomers can be either solid or microcellular, and they are suitable for production using Reaction Injection Molding (RIM) or conventional casting technology. The elastomers are useful in the production of automotive body panels, gears, seals and the like, and, since the elastomers are thermoplastic, any excess elastomer ("scrap") can be reused.
