Abstract
PURPOSE: To obtain the titled polymer having high stereospecificity in high yield, by using a preliminarily activated catalyst obtained by blending a TiCl3-containing composition prepared by reducing TiCl4 with a specific metal with an organoaluminum compound, an α-olefin, and a reaction product of an organoaluminum compound and electron donor in a specific ratio.
CONSTITUTION: An α-olefin (e.g., propylene, etc.) is polymerized by using a catalyst obtained by blending (A) a solid reaction product containing titanium trichloride prepared by reducing titanium tetrachloride with a metal of Ia, IIa, or IIIa group of periodic table, followed by granulating treatment or heat treatment, or a solid reaction product obtained by reacting the solid reaction product with an electron donor (e.g., diisoamyl ether, etc.) or electron acceptor (e.g., titanium tetrachloride, etc.), or a reaction product of an electron donor with an electron acceptor (B) an organoaluminum compound, α-olefin, and a reaction product of an organoaluminum compound and an electron donor in a molar ratio of component B to A of a 0.01W5.
