PROCESS FOR THE PREPARATION OF A CATALYST COMPONENT FOR THE POLYMERIZATION OF OLEFINS |
摘要 |
A solid catalyst component comprising the product of a process comprising (a) reacting a magnesium alcoholate of formula Mg(OR1)(OR2) compound, in which R1 and R2 are identical or different and are each an alkyl radical having 1 to 10 carbon atoms, with titanium tetrachloride carried out in a hydrocarbon at a temperature of 50-100° C., (b) subjecting the reaction mixture obtained in (a) to a heat treatment at a temperature of 110° C. to 200° C. for a time ranging from 3 to 25 hours (c) isolating and washing with a hydrocarbon the solid obtained in (b), said solid catalyst component having a Cl/Ti molar ratio higher than 2.5. |
