The invention discloses polyester based polyurethane microcellular elastomers, suitable for shoe soles, with intrinsic hydrolytic stability prepared by the reaction of a polyisocyanate with and isocyanate reactive composition. The elastomers are produced from a polyisocyanate which is an isocyanate terminated prepolymer containing a polyether polyols and the isocyanate reactive composition is a polyester formed from dimer fatty acids. |
