摘　　要：利用过程强化技术制备了UHMWPE催化剂QTE-1,并进行了小试聚合评价,重点考察了过程强化技术以及聚合温度、聚合压力等工艺条件对其性能的影响。研究结果表明,QTE-1催化剂具有聚合活性高、反应动力学曲线平稳、活性衰减缓慢等特点,聚合所得树脂性能优异。QTE-1 catalyst for production of ultra high molecular weight polyetnylene was prepared by adopting process intensification technology. Using laboratory polymerization evaluation device, the process conditions including process intensification technology, polymerization temperature, pressure and etc. were studied emphatically to understand their effects on the catalyst performances. The study results showed QTE-1 catalyst had the following features involving high reactivity, stable reaction kinetics and slow decay of activity, excellent properties of polymerized resin.
