    摘要: Olefins are polymerized by novel transition metal complexes of selected iminocarboxylate and iminoamido ligands, sometimes in the presence of cocatalysts such as alkylaluminum compounds or neutral Lewis acids. Olefins which may be (co)polymerized include ethylene, null-olefins, and olefins containing polar groups such as olefinic esters for example acrylate esters. Also described are certain nullZwitterionicnull transition metal complexes as polymerization catalysts for making polar copolymers. The resulting polymers are useful as thermoplastics and elastomers.

    摘要: Mixtures of different polyolefins may be made by direct, preferably simultaneous, polymerization of one or more polymerizable olefins using two or more transition metal containing active polymerization catalyst systems, one of which contains nickel complexed to selected ligands. The polyolefin products may have polymers that vary in molecular weight, molecular weight distribution, crystallinity, or other gala factors, and are useful as molding resins and for films.
