Abstract: The present invention relates to novel thermoplastic polyurethane compositions made from the reaction product of an isocyanate component comprising hexamethylene-1,6-diisocyanate, a polyol component, and a chain extender component comprising an alkylene substituted spirocyclic compound. The present invention provides for thermoplastic polyurethane compositions which is resistant to chemical degradation and stains.

Abstract: The present invention relates to novel thermoplastic polyurethane (TPU) compositions that contain alkylene substituted spirocyclic compounds as chain extender, aliphatic polyisocyanate, and polyester polyol. The present invention provides for TPUs which exhibit high temperature and chemical resistance.

Abstract: The thermoplastic polyurethane (TPU) compositions described herein have a very good snap back properties (also called rebound resilience) while still maintaining a good combination of other properties, including hardness, low-temperature flexibility, abrasion resistance, weather-ability, low density, or any combination thereof. This combination of properties make the TPU compositions described herein useful materials for applications where polyamide copolymers (COPA) and/or polyether block amide (PEBA) materials have traditionally been used over TPU.

Abstract: The present invention relates to novel thermoplastic polyurethane (TPU) compositions that have crystalline chain ends. The TPU compositions of the invention can provide improved resiliency, lower surface free energy, and/or reduced stickiness, while maintaining other desirable physical properties. The TPU compositions of the present invention are made from the reaction product of an aliphatic polyisocyanate, a polycaprolactone polyester polyol, an optional chain extender component, and a chain terminator component, which comprises a short chain crystalline compound containing a single functional group capable of terminating the chain of the thermoplastic polyurethane.
