## Abstract Segmented poly(urethane urea)s (PUUs) with hard segments derived only from methyl 2,6โ€diisocyantohexanoate (LDI) without the use of a chain extender have previously been described. These materials, which contain hard segments with multiple urea linkages, show exceptionally high strain c
