Procedure and means for adding coordination catalyst in powder from into a continuously operating pressurized reactor

Abstract From the Canadian patent

A method and apparatus are disclosed for adding coordination catalyst in powder form to 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 where the, wax dissolves and the catalyst is set free. The rate at which coordination catalyst suspended in wax is added into the reactor is regulated by changing the pumping rate of the inert fluid. For inert fluid is used dried and nitrogenated heptane and for wax, polyethylene wax. The means comprises a catalyst adding tube connected to the polymerizing reactor containing coordina-, tion catalyst …
