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.

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 ...

The Photochemistry of Metallocenes

Russian Chemical Reviews, 1984
The problems of the photochemistry of the dicyclopentadienyl derivatives of Group VIII metals are considered. Examples of the use of the photochemical reactions of metallocenes for the preparation of light-sensitive materials, inhibitors of the photo-ageing of polymers, catalysts of the photodecomposition of polymers, etc. are presented.
