ABSTRACT:
A process for the polymerization of olefins comprises contacting at least one olefin with a catalyst prepared by impregnating a support with an aqueous solution of a magnesium compound, drying, treating the dried support with a chlorinating agent, then treating with alcohol, then treating with an etching agent capable of removing residual alcohol, then activating with a halide or haloalkoxide of Ti.
