<p>This invention is an antistatic polyurethane shoe sole which is prepared by reacting in a closed mold a reaction mixture comprising (a) a relatively high equivalent weight polyester polyol or a relatively high equivalent weight polyether polyol containing 5-25 weight percent repeating units derived from ethylene oxide and 75-79 weight percent repeating units derived from a C3-C6 cyclic ether. (b) a chain extender compound, in an amount of from 5 to 40 parts per 100 parts of component (a), (c) a sufficient amount of a blowing agent to provide a density of 10 to 65 pounds per cubic foot, (d) a polyisocyanate, in an amount to provide 0.9 to 1.2 isocyanate groups per active hydrogen-containing group present in the reaction mixture, and i</p> |
