Katalytisk komponent for polymerisering av olefiner, oppnådd ved impregnering av en forpolymer med en opplösning av en katalytisk komponent samt den fra komponenten oppnådde forpolymer

摘要

The present invention relates to a catalytic component of the polymerization of olefins combining several catalytic components of the polymerization of olefins. 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 present invention provides a control of the combination of different catalytic components and provides an improvement of the control of the quality of the polymers produced by virtue of the catalytic action of the catalytic components associated. Another advantage of the invention is to be able to control the morphology and particle size distribution of the polymers by choosing the shape of a single catalytic component. The prepolymer and the polymer obtained from the catalytic component according to the invention are also of the objects of the present invention.
