7. A general characteristic of these systems is that they are highly exothermic, as expected for reactions with productivities of more than 2.8 ton of polyethylene by mole of nickel and by hour. When the catalyst, the cocatalyst and the monomer were mixed, the reaction temperature increases, reaching a maximum value that can be 50 °C higher than the initial reaction temperature
