SOLID ALPHA-OLEFIN POLYMERIZATION CATALYST COMPONENTS |
摘要 |
A process for preparing a solid catalyst component which comprises halogenating a magnesium compound in the formula MgRR1.nCO2 in which R and R1 are the same or different alkoxy or phenoxy groups and n is a number of from 0 to 2 with a halide of tetravalent titanium in the presence of dialkylester of a dihydric aromatic carboxylic acid and an inert hydrocarbon diluent by reacting at a temperature of from 120 to 136 .degree.C and recovering the solid reaction product from the reaction mixture.
