Toluene → HCID 86742816, compound

To the above described solid component were added 40 ml of toluene and titanium tetrachloride so as to give a titanium chloride/toluene volume ratio of 3/2, the temperature being then raised to 80° C. While stirring, a mixed solution of 2 ml of di-n-butyl phthalate and 5 ml of toluene was dropwise added thereto and stirred at 80° C. for 2 hours. The resulting solid material was separated by filtration and washed with 100 ml of toluene 2 times at 75° C. Furthermore, titanium tetrachloride was added thereto so as to give a titanium tetrachloride/toluene volume ratio of 3/2 and stirred at 80° C. for 2 hours. The resulting solid material was separated by filtration at 80° C. and then washed with 100 ml of n-hexane at room temperature 7 times, thus obtaining 3.4 g of a catalyst component.
