Abstract
A process for producing a polyethylene composition which comprises polymerizing ethylene in the presence of a catalyst comprising (A) a contact treatment product of (a) a high activity catalyst component and (b) a filler, and (B) an organoaluminum compound. This process has no need for a deashing step, i.e., a step to remove the catalyst after polymerization, since the catalyst has a remarkably high activity. In the polyethylene composition produced, the filler is dispersed uniformly and the separation of the filler from the polyethylene is scarcely observed.
