Thermoplastic polyurethane elastomers with unique structure and morphology were prepared from the modified oleic acid. The hardness and mechanical properties were controlled by adjusting soft segment concentration. Segmented polyurethanes with 50 and 70% soft segment concentration ( SSC ) were prepared using the prepolymer method by reacting polyester polyol with diphenylmethane diisocyanate ( MDI ) and 1,4‐butanediol as chain extender. Thermal and mechanical properties of polymers indicated good micro‐phase separation.
