THE PRECESS FOR THE PREPARATION OF SOLID CATALYSTS FOR OLEFIN POLYMERIZATION

摘要

PURPOSE: A solid catalyst useful in the olefine polymerization process is provided to accomplish high polymerizing activity without requiring alternative treatment for removing residual catalysts by reacting the compounds including electron donor, in combination with metal and alkoxyl group, magnesium halide, alkyl metal compound, titanium halide derivative. CONSTITUTION: A solid catalyst used in the polymerization of olefins comprises the compound A having the VA or VIA family elements on the periodic table as the electron donor; the compound B having the combined material of IB-IVB family metals and the alkoxy group and magnesium halide C. The three compounds react together to form a semi-product under the semi-recrystallization process. The semi-product is added with the alkyl metallic compound D of formula M(R)n (wherein M=Mg, B, Al, Zn) to be fully semi-recrystalized and react with the titanium halide derivative E. The resultant product is washed with any suitable solvent to form the final solid catalyst product. Both of the compounds A and B is contained in an amount of 1x10¬-4 to 30 moles and 1x10¬-2 to 10 moles in terms of 1 mole of the compound C.
