摘要：
Isoprene polymerization was conducted in the cis-1,4-selective manner by combining neodymium chloride with 8-hydroxyquinoline derivatives and activating the system with triisobutylaluminium. The neodymium-based complex pre-catalysts with 8-hydroxyquinoline derivatives were synthesized and characterized as well as the molecular structure of a representative complex using single-crystal X-ray diffraction. All complexes exhibited high activity and stereospecificity (up to 97.3%) towards isoprene polymers with high molecular weight (10(5) g mol(-1)). The Al/Nd and isoprene/Nd molar ratios, reaction temperature and influence of 8-hydroxyquinoline substituents were investigated for correlations with catalytic activities and molecular weights of the polyisoprenes obtained.
