Polyethylene (PE) with bimodal molecular weight distribution has intrigued researchers because of its significant processability and mechanical properties. Novel SiO2‐supported chromocene (S‐9)/vanadium (V) bimetallic catalysts utilizing the different hydrogen response for producing bimodal PE are successfully synthesized and studied systematically. The catalysts are prepared through using the residual hydroxyl groups on the surface of SiO2‐supported vanadium catalyst to introduce chromocene. Both of the low molecular weight (MW) fraction and the high MW fraction can be controlled through adjusting the loading of bimetallic active centers. The bimetallic catalysts also show good 1‐hexene incorporation ability in ethylene/1‐hexene copolymerization.

新型SiO2支撑的二茂铬和钒双金属催化剂生产双峰聚乙烯
具有双峰分子量分布的聚乙烯（PE）由于其显着的可加工性和机械性能而吸引了研究人员。成功地合成并系统研究了新型的SiO 2负载的二茂铬（S-9）/钒（V）双金属催化剂，该催化剂利用不同的氢响应来生产双峰PE。催化剂是通过使用SiO 2负载的钒催化剂表面上的残留羟基引入二茂铬而制备的。可以通过调节双金属活性中心的负载来控制低分子量（MW）部分和高MW部分。双金属催化剂在乙烯/ 1-己烯共聚中也显示出良好的1-己烯结合能力。
