Abstract: In this paper, the polymerization of theasaponins and propylene oxide with specific catalyst described. Via ring-opening polymerization, a new polyetherified derivative of theasaponins which has perfect lipophilicity was obtained. The surface activity of the polyethers was similar to that of theasaponins. Finally the influence of the technologic conditions such as temperature, pressure, and dosage of catalyst on polymerization rate was discussed. In addition the surface activity of the derivatives of theasaponins was discussed.

Key words: Theasaponins, Polymerization, Polyethers derivative, Lipophilicity, Surface activity
