A METHOD FOR PREPARING A SOLID CATALYST FOR PROPYLENE POLYMERIZATION

摘要

PURPOSE: A Manufacturing method of solid catalyst for propylene polymerization is provided to manufacture a solid catalyst having excellent tacticity with high yield. CONSTITUTION: A Manufacturing method of solid catalyst for propylene polymerization comprises: a step of reacting titanium halide compound and dialkoxy magnesium under the presence of organic solvent; a step of reacting non-aromatic electron donor compound selected from spiro-cycloalkyane dicarboxylate compounds in the general formula (II), (III) or (IV); a step if reacting the compounds with a titanium halide compound. In the general formulas, R1, R2, R3 and R4 is C1-10 linear, branched, cyclic alkyl group or the hydrogen, n is natural number of 1-10.
