METALOCENE, CATALYST SYSTEM, AND PROCESS FOR THE COPOLIMERIZATION OF PROPYLENE WITH ETHYLENE

摘要

"process for the polymerization of olefins, in particular for the copolymerization of propylene with at least one additional olefin, compound, catalyst system, compound and system uses, process for preparing a random propylene polyolefin, homopolymer or copolymer, copolymer of high-impact propylene, use thereof, and random propylene-ethylene copolymer ". The invention relates to a method for polymerizing olefins, in particular to a method for copolymerizing propylene with additional olefins. The invention also relates to specially selected metallocenes, in particular those types of metallocenes which have different substitutions at position 2 and position 4 in the indenyl ligand, for ligand systems, for highly active catalytic systems and for new polypropylene copolymers. inventive polymerization occurs in the presence of specially selected metallocenes.
