近年来,对于稀土Ziegler-Natta催化剂活性体的研究比较活跃。使用催化剂活性体可以消除剩余烷基铝等因素对聚合反应的影响,比以前所用的多组分混合物的催化体系更客观地反映出聚合过程。我们在以前工作的基础上,从体系中分离出Nd-Al双金属活性体,并用于引发异戊二烯溶液聚合,探讨不同聚合条件下异戊二烯溶液聚合的规律,以利于对稀土催化聚合反应的深入了解。 In recent years, active rare earth Ziegler-Natta catalyst active relatively active. The use of catalyst activator can eliminate the influence of residual aluminum alkyl and other factors on the polymerization reaction and reflect the polymerization process more objectively than the catalytic system of the multi-component mixture previously used. Based on our previous work, we isolated Nd-Al bimetallic actives from the system and used them to initiate isoprene solution polymerization to investigate the polymerization of isoprene solution under different polymerization conditions to facilitate the catalytic effect of rare earth In-depth understanding of polymerization.
