摘要：
Described herein are modified thermoplastic polyurethanes, methods of reactively extruding the modified thermoplastic polyurethanes, and methods of using the modified thermoplastic polyurethanes. The modified thermoplastic polyurethanes are micro-crosslinked through reaction with a functional polyolefin, have significantly improved tensile strength and elongation compared to unmodified thermoplastic polyurethanes, and may be extruded.
