Translated abstract:
In the presented work here, new polyaromatic alpha-diimine nickel(II) complexes were successfully snythesized. The latter complexes were supported on silica gels and used to perform polymerization of ethylene in gas-phase. The microstructure as well as the melting behavior of the polyethylenes could be controlled and tailor-made by ligand design. Additionally, electron and video microscopy allowed a deeper insight into particle composition and morphology.
