A comprehensive discussion is provided of the critical physical, chemical and structural parameters, such as soft and hard segment structures and their molecular weights, polymer composition, solubility parameters, competitive intermolecular interactions and others, which strongly affect the morphology and bulk and surface properties of segmented thermoplastic polyurethanes, polyureas and poly-urethaneureas (TPUs). Important developments related to the design, synthesis and structure-property behavior of segmented polyurethanes are discussed. Although the main emphasis is placed on linear materials, some brief comments are also given on the effect of chemical crosslinking on the structure property behavior of segmented polyurethanes.
