Cationic Oligomerization of Ethylene Oxide

Intelligent catalysts for ethylene oligomerization and polymerization

EEthylene polymerization catalysts became available in an enormous variety. The challenge in this research is to find catalysts that are able to connect ethylene molecules in such a way that not only linear chains are produced but variations like branched materials that possess very interesting mechanical properties like linear low density polyethylene (LLDPE). In this contribution, three diffe...

Development of Tantalum Phenoxy-Imine Compounds for Selective Ethylene Oligomerization

The Selective Oligomerization of Ethylene Using Chromium Diphosphine Catalysts

A series of bis(diphenylphosphino)amine ligands with a donor group attached to the nitrogen linker have been prepared. Metalation of these ligands with chromium trichloride provides precursors to highly active, relatively stable, and selective catalysts for trimerization and tetramerization of ethylene. It has been demonstrated in oligomerization reactions performed at 1 and 4 atm of ethylene t...
