Double Metallocene Nanowires

Journal of the American Chemical Society, 2009
The structural, electronic, and magnetic properties of double metallocene nanowires PnM(2) (Pn = C(8)H(6), M = V, Cr, Mn, Co, and Ni) are investigated within the framework of gradient-corrected density functional theory. The PnMn(2) nanowire is predicted to be ferromagnetic while other nanowires are either antiferromagnitic or nonmagnetic. In addition,

Polyethylene waxes by metallocenes

Polymers for Advanced Technologies, 2011
AbstractThe syntheses of low‐molecular‐weight polyethylene (PE), in the presence of catalysts based on five different metallocene frameworks, have been compared. High yields and low molecular masses, typical of industrially relevant PE waxes, can be easily achieved by using overpressure of hydrogen.

Metallocene-containing conjugated polymers

Advances in Colloid and Interface Science, 2008
The paper gives a review of publications on polymers with conjugated matrices (PPy, PTh, PAni, hydrocarbon or mixed chains...) which incorporate metallocene complexes (Fe, Ru, Co; Ni, Ti, Zr, Ta) with two cyclopentadienyl ligands (Cp) and their derivatives, in particular with methylated cyclopentadienyl rings (Cp*), as well as hemi-metallocene ...

Water‐Soluble Metallocene‐Containing Polymers

Macromolecular Rapid Communications, 2016
Metallocenes are organometallic compounds with reversible redox profiles and tunable oxidation and reduction potentials, depending on the metal and substituents at the cyclopentadienyl rings. Metallocenes have been introduced in macromolecules to combine the redox‐activity with polymer properties.

Key intermediates in metallocene-and post-metallocene-catalyzed polymerization

Kinetics and Catalysis, 2007
The structures of intermediates formed upon the activation by methylaluminoxane (MAO) of a wide range of metallocene and post-metallocene catalysts of olefin polymerization were studied by 13C, 1H, and 19F NMR. For all metallocenes considered (L2ZrCl2 and L2TiCl2), under conditions similar to real polymerization conditions (Al/Zr > 200), two types of ...

Metallocene industriell

Nachrichten aus Chemie, Technik und Laboratorium, 1995
AbstractDurch technische Umsetzung der mit Metallocenen katalysierten Polymerisation will Hoechst im europäischen Polypropylen‐Geschäft die Nr. 1 werden. Metallocen‐Katalysatoren sollen zur Realisierung von drop in‐Technologien auch an Wettbewerber verkauft werden. Neue Cycloolefin‐Copolymere versprechen eine globale Spitzenposition.
