Abstract
PURPOSE: To prepare the titled polymer having remarkably improved stereo-regurality, in high yield, by using a catalyst composed of an organic aluminum compound and a component obtained by pulverizing titanium trichloride in the presence of an organic aluminum compound under specific conditions, and treating the product successively with titanium tetrahalide and an electron donor.
CONSTITUTION: A ≥3C α-olefin is (co)polymerized using a catalyst composed of (A) a modified titanium trichloride composition prepared by (1) pulverizing a titanium trichloride composition used as the raw material in the presence of an organic aluminum compound (e.g. ethyl aluminum dichloride) until the X-ray patterns of the α- or γ-type crystal of the titanium trichloride component exsisting in the composition become unidentifiable, (2) contacting the powder with a titanium tetrahalide (e.g. titanium tetrachloride), and (3) extracting and washing the product with an inert solvent (e.g. toluene) containing an electron donor (e.g. anisole), and (B) an organic aluminum compound (e.g. diethyl aluminum chloride).
