摘要：

Catalysts based on non-bulky neodymocenes lead to butadiene-ethylene copolymers with up to 40 mol% of inserted butadiene. The catalyst was developed based on a neutral base-free neodymocene complex and an alkylating agent. The coordinated butadiene was not easy to insert into the metal carbon bond. Hydrogen was added to resume polymerization immediately. A bridged complex was also synthesized. The ligand's electronic effects were verified.
