摘要
烯烃原料组成是影响PAO合成油性能的关键因素,文章以三氟化硼为催化剂对不同平均碳数组成的α-烯烃聚合进行了研究。实验结果表明,混合α-烯烃的平均碳数对聚合产物的性质影响显著:平均碳数越大,黏度指数越高,倾点越低。通过调节混合α-烯烃的平均碳数,可以获得不同产品特点的聚合产物,满足不同的应用需求。
Alpha-olef in composition is a key factor affecting the performance of PAO synthetic oil. In this paper,boron trifluoride was used as catalyst for the polymerization of alphaolefins with different average carbon number.The results show that the average carbon number of mixed alpha-olefins has a significant effect on the properties of the polymer products,the higher the average carbon number,the higher the viscosity index and the lower the pour point.By adjusting the average carbon number of mixed alpha-olefins,the polymer products with different product characteristics can be obtained to meet different application requirements.
