29. Please note that the catalytic polymerization reactions of ethylene discussed differ from typical free-radical miniemulsion polymerization of a preformed miniemulsion of a liquid monomer. Gaseous ethylene monomer is fed continuously to the reaction mixture subsequently to miniemulsification of the catalyst solution.
30. [4,11] the necessity of a certain amount of liquid hydrocarbon for any efficient ethylene polymerization remains questionable.
31. Ethylene polymerization by water-soluble complexes has been demonstrated:see reference [4a] and F. M. Bauers, PhD thesis, University of Freiburg (Germany), 2003. However, low polymer yields in combination with the synthetic effort for the catalyst precursors hampered any further studies.
32. Microtome cuts were investigated, as in regular TEM aggregation of the sample during preparation hampered its analysis.
33. Such elevated temperatures are beneficial to any technical-scale polymerization process to enable removal of the heat of reaction without the need of energy-consuming refrigeration of the coolant.
