Catalyst for the polymerization of ethylene, its preparation and the use of the resulting ethylene polymers for the production of films exhibiting little blocking |
| abstract |
A catalyst for the copoly-merization of ethylene by the gas-phase fluidized-bed method is prepared by a process in which a titanium-containing and magnesium-containing active component, reacted with an alcohol as a complexing agent, is applied to a finely divided silica from homogeneous solution, in the presence of a polysiloxane, by evaporating the sol-vent, and the resulting homogeneous catalyst intermediate is then preactivated by treatment with the alkylaluminum compound and the Lewis base in an inert hydrocarbon solution, and the copolymers prepared using the above catalyst are employed for the production of films ex-hibiting little blocking. |
