METHOD FOR POLYMERIZING OR COPOLYMERIZING PROPYLENE IN LIQUID PROPYLENE, SOLID CATALYTIC COMPONENT, AND METHOD FOR MAKING SAME, PROCESS FOR POLYMERIZATION OR COMPONATION OF PROPYLENE IN LIQUID PROPYLENE,

摘要

The present invention relates to a process for the preparation of a catalyst comprising the steps of: a. Solid compounds containing atoms of magnesium, halogens and transition metals, b. Organoaluminum derivatives, c. Formula R^OneR²Si (OR³) (OR⁴) Dialkoxysilane [wherein R³And R⁴Represents a hydrocarbon group containing 1 to 12 carbon atoms, preferably methyl or ethyl group; And R^OneAnd R²Represents a hydrocarbon group, and R^OneAnd R²In the presence of a solid catalyst component obtained by contacting with at least one of the carbon atoms in the liquid propylene.;The present invention also relates to a novel solid catalyst component for the polymerization of olefins and a process for their preparation.
