中文摘要the aryldiimine ncn-pincer stabilized neodymium dichloride combined with aluminum alkyls established a new type of homogeneous binary neutral ziegler-natta catalyst system. this system exhibited high activity and high cis-1,4 selectivity for the polymerization of isoprene (t-p = 20 degrees c, 98.2%; t-p = -20 degrees c, > 99%). such catalytic performances remained under a broad range of polymerization temperatures and monomer-to-neodymium ratios (from 500 to 8000), reaching high number-average molecular weight (m-n = 1582 kg/mol) and relatively narrow molecular weight distribution (pdi = 1.68), which was, however, influenced by the amount and bulkiness of aluminum alkyls. dynamic investigation of the polymerization was performed, which showed the number-average molecular weight of the resultant polyisoprene had an almost linear correlation with the conversion, suggesting, in some degree, the polymerization with this catalytic system was controllable.
