Process for activating catalyst for polymerization of propylene before polymerization |
| abstract |
A method for activating a catalyst for propylene polymerization before polymerization is proposed. According to this method, a catalyst which has stability at the time of use and reduces the ratio of amorphous polymer at the time of polymerization is obtained. Said method comprises causing a catalyst dispersion prepared by mixing a specified delta -type titanium trichloride composition and an alkylaluminum trichloride in an inert solvent and maintained at a temperature of 10 DEG to 50 DEG C, to absorb a small amount of propylene in an amount of 0.5 to 5 times by weight that of said delta -type titanium trichloride. |
