Organische Trägermaterialien für Ziegler-Natta-Katalysatoren
, 2017 Ziel dieser Arbeit war die Entwicklung eines auf einem organischen Trägermaterial basierenden Ziegler-Natta-Katalysatorsystems, welches die erforderliche Fragmentierbarkeit in möglichst kleine Fragmente aufweist. Hierfür sah das Konzept dieser Arbeit eine direkte Bildung der aktiven Zentren auf fein dispergierten, Hydroxy-funktionalisierten Polystyrol ...

Water-accelerated organic transformations [PDF]
, 2001 Rather than quenching all reactive intermediates and arresting the reaction, the addition of catalytic or stoichiometric (1-10 equiv.) quantities of H2O to organic and organometallic processes can lead to surprisingly beneficial effects on reaction rate,
