1-Hexene Polymerization Initiated by α-Diimine [N,N] Nickel Dibromide / MAO Catalytic Systems : Inflg different alkyl groups (R= Me, iPr, tBu) on the phenyl ligand. Methylaluminoxane (MAO) was used as an activator. Kinetic and UV/visible spectroscopic studies show the strong influence of the phenyl alkyl substituents of the diimine ligands onto the polymerization process as well as on the polyhexenes characteristics.作者: staging 時(shí)間: 2025-3-22 07:27

Activation of Siloxy-substituted Compounds and Homopolymerisation of Ethylene by Different Soluble Aene compounds. However, surprisingly few studies on different coactivators have been published. The most well known coactivator is methylalumoxane (MAO) discovered by Kaminsky. The second important activator systems for metallocenes are boron coactivators such as tris(pentafluorophenyl)borane.
