Norbornene polymerization and copolymerization with ethylene by titanium complexes bearing pyridinium imide ligand
A novel titanium complex was synthesized and characterized, and its catalytic behavior for the homopolymerization of norbornene (NB) and copolymerization with ethylene (E) was investigated. After activation with tri-isobutyl aluminum (TIBA), the titanium complex showed good activity for both homopolymerization of norbornene (NB) and copolymerization with ethylene (E), and the effect of reaction conditions on the catalytic activity was investigated. The norbornene copolymer (PNB) and norbornene-ethylene polymer (NB-E) were also characterized by nuclear magnetic resonance (1H NMR, 13C NMR), scanning electron microscopy (SEM), and thermogravimetric analysis (TGA). The results showed that PNB is an addition polymerization product of norbornene, and the insertion ratio of NB in NB-E is 83.40%. The morphology of PNB is flaky, while the morphology of NB-E is a cross-linked network. The solubility of PNB and NB-E is poor, and they have a good thermal decomposition temperature of about 400 ℃.
期刊介绍：
Transition Metal Chemistry is an international journal designed to deal with all aspects of the subject embodied in the title: the preparation of transition metal-based molecular compounds of all kinds (including complexes of the Group 12 elements), their structural, physical, kinetic, catalytic and biological properties, their use in chemical synthesis as well as their application in the widest context, their role in naturally occurring systems etc.
Manuscripts submitted to the journal should be of broad appeal to the readership and for this reason, papers which are confined to more specialised studies such as the measurement of solution phase equilibria or thermal decomposition studies, or papers which include extensive material on f-block elements, or papers dealing with non-molecular materials, will not normally be considered for publication. Work describing new ligands or coordination geometries must provide sufficient evidence for the confident assignment of structural formulae; this will usually take the form of one or more X-ray crystal structures.
