Synthesis and Evaluation of Arylimino Pyridine Nickel(II) Catalysts: Influence of Substituents on Polyethylene Structure
The asymmetric arylimino pyridine Ni(II) catalysts have been examined with different substituents including diisopropyl, diethyl, fluoro, and chloro groups. The influence of these substituents and variation of ethylene pressure on the catalytic activity, crystalline structure, as well as on thermal properties of polyethylene has been investigated.
