Abstract
In der vorliegenden Arbeit werden die Ti-katalysierte selektive Synthese verzweigter α-Olefine mit Ethylen und die Anwendung eines verzweigten α-Olefins als Monomer in der stereoregularen Polymerisation vorgestellt. Der erste Teil bilden Untersuchungen zu Ligandeffekten in der Ti-katalysierten Ethylenoligomerisation und Co-Oligomerisation mit Hex-1-en. Darauf aufbauend wird die Ethylentrimerisierung und -tetramerisierung zu 3-Methylenpentan (3MP) und 4-Ethylhex-1-en (4EH) sowie die Multigrammsynthese von 4EH beschrieben. Zuletzt wurde der einfache Zugang zu 4EH genutzt, um damit isotaktisches Poly(4-ethylhex-1-en) (i-P4EH) herzustellen und zu charakterisieren.
Abstract in another language
This work presents the Ti-catalysed selective synthesis of branched α-olefins with ethylene and the use of a branched α-olefin as a monomer in stereoregular polymerisation. The first part consists of investigations into ligand effects in Ti-catalyzed ethylene oligomerization and co-oligomerization with hex-1-ene. Based on this, the ethylene trimerisation and tetramerisation to 3-methylenepentane (3MP) and 4-ethylhex-1-ene (4EH) as well as the multigram synthesis of 4EH are described. Finally, the simple access to 4EH was used to synthesize and characterise isotactic poly(4-ethylhex-1-ene) (i-P4EH).
