Abstract

PURPOSE: To obtain finely divided solid TiCl3 suitable for use as catalyst for stereoregular polymn. of α-olefins by treating TiCl4 with an org. Al cpd. in the presence of a thioether and bringing the resulting liquid substance into contact with a liberating agent at below a specific temp.
CONSTITUTION: TiCl4 is reduced in the presence of a thioether such as diethyl ether with an org. Al cpd. such as triethyl aluminum diluted with a hydrocarbon solvent such as n-pentane. The resulting liquid substance optionally mixed with the above diluent is brought into contact with a liberating agent at below 150, pref. 40W150°C to precipitate finely divided solid TiCl3. The agent may be Lewis acid such as TiCL4 or BF3 stronger than TiCl3. The above precipitates are then separated and washed to obtain purple TiCl3 catalyst. The catalyst shown high polymn. activity as α-olefin polymn. catalyst and can give polymers of good stereoregularity.
