摘要：
Surface pressure- area isotherms of cellulose triacetate and amylose triacetate at the air- water interface were determined on a vertical and horizontal film balance. Both polymers show anomalous behavior on the vertical balance, including- higher compressibilities than obtained on the horizontal balance, movement of the vertical plate, and atypical hysteresis of the isotherms. A helical conformation for amylose triacetate at the air- water interface is proposed t explain the low compressibility of this monolayer.
