摘 要:用限制几何构型的茂金属催化体系2-Me4Cp-4,6-tBu2-PhOTiCl2/Al(iBu)3/Ph3C+B(C6F5)4-对1-癸烯的齐聚进行了研究。探讨了Al与Ti摩尔比和反应温度对聚合反应的影响。用GC和13CNMR表征了聚合物组成和结构。结果表明,聚合物主要是二聚物、三聚物、四聚物、五聚物。该齐聚物具有高黏度指数(VI=238)、低凝点(≤-62℃)的性质,是理想的润滑油基础油组分。Oligomerization of 1-decene catalyzed by metallocene with constrained geometry, 2-Me4Cp-4, 6-tBuE-PhOTiClz/AI(iBu)31Ph3C+B(C6F5)4-, was studied. Effects of Al/Ti mole ratio and oligomerization temperature on 1-decene polymerization were investigated. The composition and structure of the obtained product were characterized by GC and 13C NMR methods. The results showed that the obtained product is a mixture mainly composed of dimer, trimer, tetramer and pentamer. This oligomer mixture has a high viscosity index (VI=238) and a low solidifying point (≤-62℃), which is a desired component for lubricant base oil.
