POLYETHYLENE AND CATALYST COMPOSITION FOR POLYETHYLENE SYNTHESIS

摘要

FIELD: chemistry. ^ SUBSTANCE: invention relates to a polyolefin synthesis method and more specifically to a polyethylene synthesis method. Polyethylene is a copolymer of ethylene with 1-alkenes. The invention also relates to polyethylene synthesis catalyst systems. The catalyst system is a mixture of metallocenes: hafnocene and an iron-based complex, an activating compound and a support. The invention also relates to films made from polyethylene and packets made from the said films. ^ EFFECT: disclosed catalyst system enables production of polyethylene with given molecular weight distribution in a single reactor. ^ 16 cl, 3 tbl, 3 ex
