    摘要: Catalyst systems useful for olefin polymerization are disclosed. The catalysts include a bimetallic complex that incorporates two linked indenoindolyl groups, each of which is pi-bonded through its cyclopentadienyl ring to one of the metals. Compared with conventional indenoindolyl complexes, the bimetallic complexes of the invention have enhanced ability to give polyolefins with desirably low melt indices. Certain bimetallic indenoindolyl complexes also provide a way to broaden polymer molecular weight distribution and thereby improve processability simply by regulating the amounts of comonomer and activator used in the polymerization.

    摘要: An olefin polymerization process is disclosed. The process comprises polymerizing olefins in the presence of a supported indenoindolyl catalyst system and an organoboron or organoaluminum-treated solid. The supported indenoindolyl catalyst system comprises a support, an organometallic complex comprising a Group 3 to 10 transition or lanthanide metal, M, and at least one indenoindolyl ligand that is &pgr;-bonded to M, and an activator. Performing the process in the presence of the organoboron or organoaluminum-treated solid surprisingly leads to an increased activity compared to polymerization processes performed without the treated solid.

    摘要: An ethylene polymerization catalyst and catalyst system which produces ethylene copolymers having unique melt elastic properties at high catalytic activity. The catalyst is produced by the steps which include contacting silica having a surface area of between above about 500 m2/g and about 800 m2/g, a particle size in the range of between about 10 microns and about 200 microns and a pore volume of between about 0.5 cc/g and about 3.0 cc/g with an organosilicon compound. This product is contacted with a dialkylmagnesium compound or complex. The product of this step, in turn, is contacted with an alcohol or silane compound. Finally, the thus formed product is contacted with a transition metal compound.

    摘要: An ethylene polymerization catalyst and a catalyst system which provides an ethylene copolymer which, when formed into a film, is characterized by the combination of high stiffness and impact strength. The ethylene polymerization catalyst is formed by contacting a support with an organosilicon compound. The so-treated support is thereupon contacted, in a second step, with a dialkylmagnesium compound or complex. In a third step, the product of the second step is contacted with an alcohol or silane compound. This product, in turn, in a fourth step, is contacted with a transition metal compound. Finally, in a fifth and concluding step, the product of the fourth step is contacted with a Group 13 metal-containing compound. The second and third, as well as the third and fourth contacting steps may be reversed.
