Abstract
Procedure and means for adding coordination catalyst in powder form into a pressurized polymerizing reactor. The coordination catalyst in powder form is suspended in fluid wax. The mixture of catalyst and wax is pumped with the aid of an inert fluid into the polymerizing reactor (11), where the wax dissolves and the catalyst is set free. The rate at which coordination catalyst (13) suspended in wax is added into the reactor (11) is regulated by changing the pumping rate of the inert fluid. For inert fluid is used dried and nitrogenated heptane (18) and for wax, polyethylene wax. The means (10) comprises a catalyst adding tube (12) connected to the polymerizing reactor (11), containing coordination catalyst in powder form suspended in wax, and means for pumping inert fluid into the adding tube (12) and for feeding the mixture into the polymerizing reactor (11).
