Ligand steric effects on naphthyl-alpha-diimine nickel catalyzed alpha-olefin polymerization
Naphthyl-a-diimine nickel complexes with systematically varied ligand sterics, activated by modified methylaluminoxane (MMAO), were tested in the polymerization of higher a-olefin (1-hexene, 1-decene and 1-hexadecene) under suitable conditions. The polymerization results indicated the possibility of precise microstructure control, depending on catalyst structure, polymerization temperature, monomer concentration and types of monomers, which in turn strongly affects the resultant polymer properties. Naphthyl-a-diimine nickel complex bearing chiral bulky sec-phenethyl groups in the o-naphthyl position showed good catalytic activity, and resulted in branched polymers (42-88/1000C) with high molecular weights (M (n): (4.3-15.2) x 10(4) g center dot mol(-1)) and narrow molecular weight distribution (M (w)/M (n) = 1.13-1.29, RT), which suggested a living polymerization. The increasing steric hindrance of catalyst leads to enhance insertion for 2,1-insertion of a-olefin and the chain-walking reaction.
Synthetic Route of 6224-63-1, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 6224-63-1 is helpful to your research.
