以脂肪酸和多胺为原料合成多胺酰胺，用三聚甲醛进一步交联多胺酰胺，将其作为稠油流动性改进剂，评价了其对稠油凝点和粘度的影响。结果表明，三聚甲醛交联的多胺酰胺型稠油流动性改进剂有一定的降凝作用，最高为2.2℃。三聚甲醛交联的多胺酰胺型稠油流动性改进剂中脂肪酸的种类与结构对稠油的降粘效果影响较大，胺的种类与结构对稠油降粘效果影响小。三聚甲醛交联的多胺酰胺侧短烷基链(C16)的降粘效果最高达32.7%。

Polyamine amide was prepared from fatty acid, polyamine and trioxane as raw materials. The effect of flow improvers on the pour point and viscosity of heavy oil was evaluated. The result indicated this series of a new type flow improver could depress the pour point of heavy oil, among which the highest pour point depression was 2.2℃. This series of a new type flow improver also could reduce the viscosity of heavy oil. Date analysis showed that the amine structure effect on the efifciency greatly, while fatty acid structure was insigniifcant. When polyamine amide molecular main chain contained less nitrogen atoms, efifciency of short chain alkyl structure was slightly better than the long chain alkyl. But as the number of nitrogen atoms increased, efifciency of long chain alkyl structure on heavy oil viscosity reduction increased. The most effective polyamine amide showed potent viscosity reduction and the highest reduction rate of 32.7% with less nitrogen atoms and short chains.
