Abstract
PURPOSE: To prepare a highly stereoregular olefin polymer without eliminating the catalyst residue, by carrying out the polymerization in the presence of a specific dialkyl monohalide and solid titanium trichloride as the catalyst.
CONSTITUTION: Titanium tetrachloride is made to react with an organoaluminum compound in a solvent, e.g. n-hexane, etc., in the presence of ethyl ether to give liquefied titanium trichloride. Fine powdery solid titanium trichloride is precipitated by heating the liquid at ≤150°C. An ofefin, e.g. propylene, etc., is polymerized in the presence of the above solid catalyst, di-n-propylamluminum monochloride or di- n-hexylaluminum monochloride as a co-catalyst, and if necessary an electron-donative compound, e.g. ethyl benzoate, etc..
