摘要: 1-Hexene polymerization has been investigated, in cyclohexane at 20°C, the presence of (R-Phenyl)2 α-diimine[N,N] nickel dibromide catalysts bearing different alkyl groups (R= Me, iPr, tBu) on phenyl ligand. Methylaluminoxane (MAO) was used as an activator. Kinetic and UV/visible spectroscopic studies show strong influence substituents diimine ligands onto process well polyhexenes characteristics.
