Notes:
Strain birefringence of swollen sodium hyaluronate films was measured. Typical Wiener curves were obtained in solvents with different refractive indices. The orientation birefringence of sodium hyaluronate was evaluated from the minima of the Wiener curves and was found to increase with increasing elongation. Up to 30% elongation, the swollen hyaluronate films show quasi-rubberlike behavior. Above this elongation, the interchain hydrogen bonding further hinders the chain mobility and the orientation increases only slightly.
