WANG De-run, YU Xian-chao, ZHAO Da-jian. STUDY ON CONFORMATIONS OF XANTHAN MOLECULES IN AQUEOUS SOLUTION[J]. Acta Polymerica Sinica, 1990,(3):322-326.DOI:
The conformation of xanthan molecule in aqueous solution was investigated by GPC. It is indicated that two states of xanthan exist simultaneously in aqueous solution at low ion-intensity. One of the two states is polyassociated double-stranded helix
and the other is single molecular state. These two states can transform each other under some conditions.
