Zirconocene Complexes with Cyclopenta[l]phenanthrene Ligands: Syntheses, Structural Dynamics, and Properties as Olefin Polymerization Catalysts

Nicole Schneider, Frank Schaper, Katrin Schmidt, Robin Kirsten et autres

(2-Methylcyclopenta[ l ]phenanthryl) 2 ZrCl 2 and (2-phenylcyclopenta[ l ]phenanthryl) 2 ZrCl 2 were synthesized and used, after activation with MAO, as catalysts for the polymerization of propene. The resulting polymers had low isotacticities (8−18% [mmmm]). Ligand rotation barriers for the corresponding …

Synthesis and properties of elastomeric poly(propylene)

Stefan Mansel, Ernesto Pérez, Rosario Benavente, José M. Pereña et autres

Elastomeric poly(propylene) with low percentages of isotactic pentads and high molecular weight was synthesized using unbridged “oscillating” metallocenes. The polymer sample with the highest [mmmm] content (22%) shows a small amount of crystallinity, which is highly influenced by the thermal history, and …

Influence of Ramipril on Renal Function in Patients with Chronic Congestive Heart Failure

Bernhard Heintz, M. Verho, D. Brockmeier, Robin Kirsten et autres

Ramipril was administered to 13 patients, aged 49–80 years, weighing 53.5–90.3 kg, with congestive heart failure (CHF) for 2 weeks in an open trial. One patient dropped out after day I and another accidentally received another angiotensin-converting enzyme (ACE) inhibitor, so that …
