This invention relates to a method of fabricating an elastomer which comprises the steps of: (a) fabricating a polyol having a molecular weight of between about 400 and about 15,000 and having a level of end group unsaturation of no greater than 0.04 milliequivalents per gram of polyol, said polyol being fabricated in the presence of a double metal cyanide catalyst, (b) reacting said polyol with a polyisocyanate to produce an isocyanate-terminated prepolymer, and (c) reacting said isocyanate-terminated prepolymer with a chain extender in a mold in order to produce the elastomer. Also claimed is the elastomer produced by the above method utilizing a one-shot technique.
