| Abstract: |
| The influences of polymer 3530S and degraded polymer on the stability of oil-in-water emulsion were studied. The stability mechanism of oil-in-water emulsion was investigated using interfacial shear viscosity and zeta potential vialiie. The results indicate that inteifacial activity of polymer increases after oxidation degradation，while the stability of emulsion. weak' ened by degraded polymer. It is also indicated that stability of oil-in-waler emulsion is mainly affected by strength of the interfacial film and zeta potential value of the oil droplets. |
