摘要： A method for preparing a supported organometallic complex is disclosed. An organometallic complex is combined with a support material that has been treated with an organozinc compound. The organometallic complex comprises a Group 3 to 10 transition metal and an indenoindolyl ligand that is bonded to the transition metal. Also disclosed is a process for polymerizing an olefin using the supported complex. Organozinc treatment of the support unexpectedly boosts catalyst activity and polyolefin molecular weight.

摘要： Ethylene and optional comonomers are polymerized using a supported metallocene catalyst, an alumoxane activator, and triisobutylaluminum (TIBAL). A silica support is first pretreated with a silane compound and then with an organoboron compound. The treated silica is then combined with a Group 4 metallocene complex and an alumoxane to generate a supported, activated catalyst. While it was previously thought that the particular support treatment technique used herein provided benefits only for polymerizations catalyzed by non-metallocene single-site complexes, it has now been found that similar benefits can be realized even with conventional metallocenes if TIBAL is selected as the scavenger.

摘要： The invention relates to a process for the in-situ preparation of alkylated single-site transition metal catalysts by contacting a precatalyst which comprises halogen, alkoxy or amido group, with an alkylating agent in the polymerization system. The precatalyst, which is produced prior to introducing into the polymerization system, is obtained by contacting a transition metal complex and boron-containing ionizing agent, optionally, with a support.
