Process for polymerization of olefins and catalysts therefor
Abstract
Abstract STEREOSPECIFIC POLYMERS OF OLEFINS ARE PRODUCED WITH LITTLE FORMATION OF AMORPHOUS POLYMERS BY CONTACTING OLEFINS WITH A CATALYST COMPOSED OF (A) A TITANIUM TRICHLORIDE COMPOSITION OBTAINED BY PULVERIZING TATANIUM TRICHLORIDE IN THE PRESENCE OF AN AUXILIARY COMPONENT SELECTED FROM (1) ORGANIC OXYGEN-CONTAINING COMPOUNDS SUCH AS SATURATED ALIPHATIC MONOETHERS, (2) ORGANIC NITROGEN-CONTAINING COMPOUNDS SUCH AS SATURATED ALIPHATIC PRIMARY AMINES, (3) ORGANIC PHOSPHORUS-CONTAINING COMPOUNDS SUCH AS TRIALKYL PHOSPHINES, (4) SULFUR CONTAINING COMPOUNDS SUCH AS CARBON DISULFIDE, (5) ORGANIC SILICON-CONTAINING COMPOUNDS SUCH AS TRIARYL SILICON ISOCYANATES, AND (6) HYDROCARBONS SUCH AS SATURATED ALIPHATIC HYDROCARBON UNTIL A- OR Y-CRYSTAL TYPE OF SAID TITANIUM TRICHLORIDE CANNOT BE IDENTIFIED IN THE X-RAY DIFFRACTION PATTERN AND EXTRACTING THE RESULTING TITANIUM TRICHLORIDE COMPOSITION WITH A SOLVENT SUCH AS HYDROCARBONS, HALOGENATED HYDROCARBONS OR CARBON DISULFIDE OR MIXTURES OF THESE WITH SAID COMPONENTS (1), (2) AND/OR (5); AND (B) AN ORGANOALUMINUM COMPOUND.
