Abstract: The effect of polymer (HPAM) on the stability of the two types of W/O and O/W emulsion have been studied by using static and centrifugal method.Meanwhile,the stabilizing machenism of polymer for emulsions and liquid membranes also have been disscussed.The results indicate that the polymer obviously increases stability of O/W type emulsion or water membrane and has a little effect on W/O type emulsion or oil membrane.The interactions between polymer and adsorbent at interface are different according to the adsorbed materials.The macromolecular polymer which dissolved in water is able to form viscous film at the side of continuous phase and also increase sterical force.So the strength of water membrane is increased and the straining and breaking rate of water membrane is decreased.The higher the hydrolytic degree of polymer is,the greater it effects.
