Influence of polyethylene glycol unit on nickel catalyzed ethylene polymerization have attracted increasing interest. The Lewis basic oxygen atoms on polyethylene glycol group can form interactions with Lewis acidic metal additives. In this contribution, a series of iminopyridyl ligands (L-O1, L-O2 and L-O3) bearing polyethylene glycol units and corresponding nickel complexes (Ni-O1, Ni-O2 and Ni-O3) were designed, synthesized and characterized. By the activation of alkylaluminium cocatalysts, the nickel complexes and their corresponding MgCl2-supported nickel precatalysts (Ni-O1-Mg, Ni-O2-Mg and Ni-O3-Mg) were investigated in catalytic homogeneous and heterogeneous ethylene polymerization, resp. The mol. weight of products increased with the number of oxygen atoms on polyethylene glycol unit increasing. The introduction of the MgCl2 support resulted in much higher mol. weights and much lower branched densities of polyethylenes than those of products generated in the homogeneous polymerizations The polymers generated in heterogeneous polymerizations have excellent polymer powder morphol. to prevent reactor fouling, facilitating potential industrial applications. In the experiment, the researchers used many compounds, for example, 2-(2-Methoxyethoxy)ethanol (cas: 111-77-3Application of 111-77-3).
2-(2-Methoxyethoxy)ethanol (cas: 111-77-3) belongs to ethers. Of all the functional groups, ethers are the least reactive ones. Ether bonds are quite stable towards bases, oxidizing agents and reducing agents. Ethers can form hydrogen bonds with other molecules (alcohols, amines, etc.) that have O―H or N―H bonds. The ability to form hydrogen bonds with other compounds makes ethers particularly good solvents for a wide variety of organic compounds and a surprisingly large number of inorganic compounds.Application of 111-77-3
