Domain structure, thermal and mechanical properties of polycaprolactone-based multiblock polyurethane-ureas under control of hard and soft segment lengths

HIGHLIGHTS

SUMMARY

The absorption bands in the region of 3450-3400 cm-1 correspond to vibrations of free (non-hydrogen_bonded) N-H of urethane and urea groups. The formation of hydrogen_bonds by these groups can be judged using the absorbance, A=log10 (1/T ), on the border of SWIR/MWIR regions (ca. This means that all N-H of urethane and urea groups in these systems participate in the formation of hydrogen_bonds with oxygen of similar groups in other units or neighboring chains. It can be assumed that the enhanced interaction between the hard segments is . . .
