中文摘要：
研究了聚合物3530S及其降解后的聚合物对水包油乳状液稳定性的影响,用界面剪切粘度和zeta电位考察了水包油乳状液的稳定机理。研究发现,热氧降解后聚合物的界面活性升高,降解后的聚合物使乳状液的稳定性变差,水包油乳状液的稳定性主要由界面膜强度和油珠表面的zeta电位决定。
英文摘要：
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 value. The results indicate that interfacial activity of polymer increases after oxidation degradation, while the stability of emulsion is weakened by degraded polymer. It is also indicated that stability of oil-in-water emulsion is mainly affected by strength of the interfacial film and zeta potential value of the oil droplets.
