Definitions
- the invention relates to a polymerization process, in particular to a process for increasing the productivity of the polymerization process, and to the polymers produced by the process and to devices for carrying out the polymerization process.
- coordination catalysts e.g. Metallocene catalysts are usually used together with a cocatalyst, such as alumoxane, since the catalytic activity of the coordination catalysts is often inadequate. New coordination catalysts are being developed which have higher activity, as a result of which the addition of cocatalysts can be avoided or at least reduced.
- coordination polymerization Another disadvantage of coordination polymerization is that the coordination catalysts are very sensitive to impurities, which can lead to a considerable reduction or even inactivation of the catalytic activity.
- the invention has for its object to provide a coordination polymerization process which is characterized by particularly high activity of the coordination catalyst and thereby high productivity.
- the invention is based on the knowledge that this object can be achieved by supplying electromagnetic radiation during the coordination polymerization.
- the invention relates to a polymerization process using a coordination catalyst, the coordination catalyst and / or the monomer being exposed to electromagnetic radiation during the coordination polymerization process.
- the invention further relates to a method for increasing the productivity of a coordination catalyst in a polymerization process, the coordination catalyst and the monomer being exposed to electromagnetic radiation during the polymerization process.
- the invention further relates to a polymer which is produced by a coordination polymerization process using a coordination catalyst, the coordination catalyst and the monomer being exposed to electromagnetic radiation during the polymerization reaction.
- the invention relates to a device for a polymerization process, which comprises devices for emitting electromagnetic radiation, the radiation being directed onto the coordination catalyst and the monomer.
- Coordination polymerization is a polymerization in which the polymerization is initiated by catalysts such as Ziegler-Natta catalysts or metallocene catalysts, the newly emerging monomers being embedded between growing polymer chains and transition metal of the catalyst complex.
- catalysts such as Ziegler-Natta catalysts or metallocene catalysts
- Ionic polymerization is also subsumed under the term coordination polymerization.
- the polymerization reaction of the present invention takes place without the formation of free radicals. Furthermore, it is possible that impurities are present in the polymerization process, which can usually be contained in the raw materials.
- Coordination catalysts are understood to mean all catalysts that can be used in a coordination polymerization, in particular transition metal compounds, such as Ziegler-Natta catalysts, metallocenes, so-called late transition metal catalysts, and also chromium catalysts, nickel catalysts, vanadium catalysts and Phillips catalysts.
- transition metal compounds such as Ziegler-Natta catalysts, metallocenes, so-called late transition metal catalysts, and also chromium catalysts, nickel catalysts, vanadium catalysts and Phillips catalysts.
- Suitable Ziegler-Natta catalysts are, for example, those which combine a transition element from groups 4 to 6 of the Periodic Table (IUPAC Nomenclature of Inorganic Chemistry, 1989) as a procatalyst and a compound of a metal from Groups 1 to 3 of the periodic table contain the elements as a cocatalyst. They are preferably applied to a carrier, such as silicon dioxide. They can also contain other additives, such as electron donors. Ziegler-Natta catalysts are described, for example, in EP-A-0 261 130, the disclosure of which is expressly incorporated by reference.
- the organic transition metal compounds of the formula I represent a subgroup of the transition metal compounds:
- M is a transition metal from group 3 to 10, for example 3 to 7, such as 4 to 6, and each X is independently a monovalent anionic ligand, such as a ⁇ ligand, each L is independently an organic ligand that coordinated to M, R a bridging group which two Ligand L connects, m is 1, 2 or 3, n is 0 or 1, q is 1, 2 or 3, and m + q is equal to the valence of the metal.
- ⁇ ligand is understood to mean a group which is bonded to the metal at one or more points via a sigma bond.
- said organic transition metal compounds I are a group of compounds known as metallocenes.
- Said metallocenes carry at least one organic ligand, generally 1, 2 or 3, for example 1 or 2, which is ⁇ -bound to the metal, for example an ⁇ " ligand, such as an ⁇ 5 ligand.
- the metallocene preferably contains a transition metal from groups 4 to 6, and is suitably a titanocene, zirconocene or hafnocene which contains at least one ⁇ 5 ligand, which is, for example, an optionally substituted cyclopentadienyl, an optionally substituted indenyl, an optionally substituted tetrahydroindenyl or an optionally substituted fluorenyl ,
- the metallocene compound can have the following formula II:
- each Cp is independently an unsubstituted or substituted and / or fused homo- or heterocyclopentadienyl ligand, for example a substituted or unsubstituted cyclopentadienyl, substituted or unsubstituted indenyl or substituted or unsubstituted fluoreneyl ligand; the optional one or more.
- Substituent / substituents are preferably from halogen, hydrocarbon residue (e.g.
