A METHOD FOR PREPARATION OF A SOLID CATALYST FOR POLYMERIZATION OF PROPYLENE

摘要

PURPOSE: A method for preparing a solid catalyst for polymerization of propylene is provided to obtain a solid catalyst capable of polymerizing polypropylene having excellent tacticity at high polymerization activity. CONSTITUTION: A method for preparing a solid catalyst for polymerization of propylene comprises the steps of: (i) reacting diethoxy magnesium with titanium halide in the presence of organic solvent and titanium halide; (ii) injecting a nonaromatic inner electron donor represented by chemical formula (II) into the resultant while raising the temperature to 80~130 °C; and (iii) reacting titanium halide with the resultant in a temperature of 80~130 °C and washing the resultant.
