| 摘 要： | 以自制的限定几何构型茂金属催化剂为主催化剂,甲基铝氧烷为助催化剂,对乙烯/1-己烯共聚性能进行研究,考察溶剂、Al与Zr物质的量比、聚合温度、聚合压力和共聚单体浓度等工艺条件对催化剂活性以及聚合物性能的影响。确定乙烯/1-己烯共聚合的工艺条件为:以正庚烷为溶剂,Al与Zr物质的量比为700~1 000,聚合温度(100~120)℃,聚合压力(1.2~2.0)MPa,优选1-己烯浓度为(0.8~1.8)mol·L~(-1)。

| Abstract: | Using methylaluminoxane as the cocatalyst,ethylene/1-hexene copolymerization catalyzed by the self-made limited geometry metallocene catalyst was studied.The effects of solvents,Al/Zr molar ratios,polymerization temperatures,polymerization pressure and comonomer concentrations on the catalyst activity and polymer properties were investigated.The process condition for the copolymerization of 1-hexene with ethylene catalyzed by limited geometry metallocene catalyst was determined as follows:n-heptane as the solvent,Al/Zr molar ratio 700-1 000,polymerization temperature (100-120) ℃, polymerization pressure (1.2-2.0) MPa and 1-hexene optimal concentration (0.8-1.8) mol·L-1. |
