Abstract
The present invention provides a novel process for preparing a catalyst, preferably free of electron donor, useful in gas phase polymerization of olefins having a broad polydispersity. The catalyst is prepared by contacting a dehydrated silica support with a first alkylaluminum compound, an organic chloride, a second alkylaluminum compound and an alkylmagnesium compound, and a source of titanium.
