What is metallocene adhesive?
Metallocene hot melt adhesive is a new-generation of Packaging hot melt designed for Case and Carton Sealing. Metallocene based hot melt adhesives have excellent pot life stability, clear color, offer high heat resistance and are not prone to charring or odor.
What is a Cp ring?
Introduction. The cyclopentadienyl (Cp) ligand is a monoanionic ligand with the formula C5H5. The first characterized example of a cyclopentadienyl complex was ferrocene, Cp2Fe, which has an iron atom “sandwiched” between two planar Cp rings as shown on the left.
What is cp2 chemistry?
Cp metal complexes are mainly used as stoichiometric reagents in chemical research. Ferrocenium reagents are oxidants. Cobaltocene is a strong, soluble reductant. Derivatives of Cp2TiCl2 and Cp2ZrCl2 are the basis of some reagents in organic synthesis.
What is cyclopentadienyl used for?
Uses. Aside from serving as a precursor to cyclopentadienyl-based catalysts, the main commercial application of cyclopentadiene is as a precursor to comonomers. Semi-hydrogenation gives cyclopentene. Diels–Alder reaction with butadiene gives ethylidene norbornene, a comonomer in the production of EPDM rubbers.

What is meant by Ziegler-Natta polymerization?
In Ziegler-Natta polymerisation, monomers are treated with a catalyst, such as a mixture of titanium chloride (or related compounds, like oxovanadium chloride) with triethylaluminum (or trimethylaluminum). Other components are often added, such as magnesium chloride, to modify the catalyst and improve performance.
What is metallocene pp homopolymer?
Metallocene PP Homopolymer. Polypropylene homopolymers are thermoplastic resins produced through the polymerization of propylene. The use of metallocene catalysts in the production of these homopolymers results in resins with improved optical and processing characteristics, combined with exceptional purity.
What is the general formula for metallocene?
Metallocenes have the general formula [ (η5-C5H5)2M]. Fischer et al. first prepared the ferrocene derivatives involving Co and Ni. Often derived from substituted derivatives of cyclopentadienide, metallocenes of many elements have been prepared.
What are the properties of metallocene polymers?
For example, a wide variety of metallocene polyethylenes can be produced with very different properties ranging from very soft with low melting point to high melting point with good heat resistance. Many derivatives of early metallocenes are active catalysts for olefin polymerization.
What are the advantages of metallocene catalyzed polymerization?
The metallocene catalyzed polymerization has many advantages over traditional polymerization techniques; it results in very pure, and consistent resins with well defined properties.
