Abstract
The present invention relates to a catalytic composition for the polymerization of olefins combining a number of catalytic components for the polymerization of olefins and to a process for preparing it. The catalytic component according to the invention is obtained by impregnation of a prepolymer with a solution of a catalytic component for the polymerization of olefins. The invention brings about control of the combination of different catalytic components and provides for improvement in the control of the quality of the polymers manufactured by virtue of the catalytic action of the combined catalytic components.
