| description | The invention relates to the technical field of olefin polymerization, and discloses an alpha-olefin polymer as well as a preparation method and application thereof. The alpha-olefin polymer is formed by polymerizing at least one alpha-olefin monomer CH2 = CHR, in the alpha-olefin polymer, carbon atoms located in a main chain account for 58-87% of the number of all carbon atoms, and R is linear alkyl or alkyl with a branched chain with the number of carbon atoms larger than or equal to 2; the weight average molecular weight of the alpha-olefin polymer is between 10,000 and 250,000; the molecular weight distribution PDI of the alpha-olefin polymer is less than 3. The alpha-olefin polymer of the present invention has excellent thickening efficiency when used as a viscosity index improver for lubricating oil.
本发明涉及烯烃聚合技术领域，公开了一种α-烯烃聚合物及其制备方法和应用。该α-烯烃聚合物由至少一种α-烯烃单体CH2＝CHR聚合形成，在所述α-烯烃聚合物中，位于主链中的碳原子占所有碳原子数量的58-87％，其中，R为碳原子数≥2的线性或带有支链的烷基；所述α-烯烃聚合物的重均分子量为10,000-250,000；所述α-烯烃聚合物的分子量分布PDI＜3。本发明的α-烯烃聚合物用作润滑油的粘度指数改进剂具有优 |
