Note on The Kinetics and Mechanism of The Ethylene Polymerization

The present review focus on basic correlations concerning the ethylene polymerization behavior of a Ziegler-Natta catalyst. 50 years ago, Karl Ziegler and Giulio Natta were awarded the Nobel Prize for their discovery of the synthesis of polyethylene at low pressures and moderate high temperatures with transition-metal catalysts of the 4th group and aluminum organic compounds as cocatalysts.Polyolefins have grown to become one of the biggest of all produced polymers. This significant increase occurred due to the polyolefins inherent properties and wide range of applications. Such polyolefins could be recycled mechanically or by incineration that did not result in any toxic discharges. However, their incapability of decomposing under natural conditions caused a great deal of environmental concern for their packaging uses. Since they constitute a considerable percentage of domestic garbage, polyolefins tend to fill up landfill sites by a significant amount. Today's targets include achieving sustainable polyolefin production that can save on energy and raw material consumption for future generations.
