ABSTRACT:
Method for making crystalline polymerization catalysts is disclosed which comprises contacting the soluble complex prepared from the combination of a metal dihalide and a transition metal compound with a particulate material comprising silica to produce a solid, and then reacting the solid with an organoaluminum halide. The resulting catalyst component can be further contacted with a halide ion exchanging source selected from halides of Groups IVA and VA. Novel catalysts prepared in accordance with the invention method, polymerization processes therewith and novel polymers, having high bulk density, low levels of polymer fines, and well defined particle size and shape are also disclosed.
