Description

The invention relates to a catalyst component, Catalysts of a certain composition for the poly merization of olefins and a process for the production of Polyolefins using such a catalyst. The terms polyolefin and polymer are used according to the invention used to designate an olefin homo- or copolymer. According to the invention, the term polymerization means homo- or copolymerization of olefins.

It has been proposed as in Japanese Patent Publication Publication No. 58-19309 describes ethylene homopolymers or ethylene-α-olefin copolymers among various polyols finen using a catalyst that consists of a zirconium compound, typically one Metallocene compound, and an aluminoxane compound together puts. This prior art catalyst tends to whether probably it has good yields for the formation of homo- or Low molecular weight copolymers. Polyolefins with  high molecular weight are known using a Metallocene catalyst available. A ver However, hafnium compound used is relatively difficult to obtain and is also less catalytically active than a zirconium catalyst generally recognized in the prior art gate.

There is growing interest in using polyolefins only high molecular weight and a relatively wide molecule lar weight distribution, but also a narrow distribution the copolymer composition in the case of olefinic copo lymeren.

Therefore, there is a strong interest in developing new ones Types of catalysts to polymers that quali fulfill the requirements to be able to manufacture.

Accordingly, the object of the present invention is a new one Catalyst with increased catalytic activity to the polymer Provide olefins with which the Amount and distribution of the molecular weight of the resulting Polymers can be controlled. Furthermore, it is a task the present invention a method for the production of Polyolefins using this catalyst put.

The solution to this problem is based on the surprising Be found that polyolefins with the aforementioned Eigen properties using a specific catalyst partly in connection with a selected promoter can be held. The catalyst component becomes from one or more, at least one 2,4-pentanedionato ligand-containing zirconium, titanium and hafnium compounds gene selected.

The present invention thus relates to Catalyst component by mutual contact

• (1) at least one transition metal compound derived from the Group zirconium, titanium and hafnium is selected and contains at least one 2,4-pentanedionato ligand,
• (2) a compound of the formula Me ² (OR ² ) _m R ³ _n X ² _zmn in Me ^{2 is} a metal from main groups I to III or subgroup II, R ² and R ^{3 are} each _{hydrocarbon radicals} having 1 to 24 carbon atoms mean, X ^{2 represents} a halogen atom, m satisfies 0 mz, n satisfies 0 nz and m + n satisfies 0 m + nz, and z represents the valence of Me ² , and
• (3) a cyclic organic compound with two or more conjugated double bonds available in the molecule is.

Another object of the invention is a catalyst for the polymerization of olefins by mutual Contact

• (1) at least one transition metal compound derived from the Group zirconium, titanium and hafnium is selected and min contains a 2,4-pentanedionato ligand,
• (2) a compound of the formula Me ² (OR ² ) _m R ³ _n X ² _zmn in Me ^{2 is} a metal from main groups I to III or subgroup II, R ² and R ^{3 are} each _{hydrocarbon radicals} having 1 to 24 carbon atoms mean, X ² denotes a halogen atom, m satisfies the inequality 0 mz, n satisfies the inequality 0 nz and m + n satisfies the inequality 0 m + nz, and z denotes the valence of Me ² ,
• (3) a cyclic organic compound with two or more conjugated double bonds in the molecule, and
• (4) a modified organoaluminum compound derived from the reaction of an organoaluminum compound with water results and one or more Al-O-Al-Bin in the molecule dung is available.

Another object of the invention is a method for Production of polyolefins comprising the homopolymerisa tion of an olefin or the copolymerization of two or several olefins in the presence of a kata according to the invention lysators.

The polyolefins according to the invention have a high molecular weight lar weight, a broad molecular weight distribution and a narrow distribution of the copolymer composition. This butt polymers are generally used when processing in foils or Films advantageous because the film to film or film to film Stickiness essentially disappears.

The attached drawing shows schematically the way in which the catalyst according to the invention is produced. Which he Catalysts according to the invention are essentially made up of a selected class of catalyst components and a selected class of promoters. Of the Catalyst component used according to the invention is characterized by mutual contact (1) at least one at least one Transition metal ver containing 2,4-pentanedionato ligands bond from the group zirconium, titanium and hafnium, (2) one Compound of a formula explained later and (3) one cyclic, organic compound with two or more conjugated double bonds in the molecule.
