Abstract
PURPOSE: To obtain the titled polymer having a high stereoregularity, by using a highly active catalyst consisting of a solid catalytic component of Mg and Ti, etc. supported on a specific metallic oxide carrier and an organoaluminum compound and an electron donative compound
CONSTITUTION: An olefin is polymerized in the presence of a catalyst consisting of (A) a solid catalytic component of halides of magnesium and titanium, e.g. MgCl2 and TiCl4, and an electron donative compound, e.g. ethyl benzoate, supported on at least one metallic oxide carrier consisting of SiO2, Al2O3, MgO, TiO2 or B2O3, a compound oxide thereof, e.g. SiO2.3MgO, and a mixture thereof, containing 60wt% or more particles having a particle diameter of 5W150μ, (B) an organoaluminum compound of the formula (R is H, 1W20C alkyl, etc.; X is halogen; 0<n≤3), e.g. (C2H5)3Al, and (C) an electron donative compound, e.g. an ester of a monohydric alcohol with an α,β-unsaturated monocarboxylic acid including an aromatic unsaturation such as ethyl p-toluylate.
