Abstract
PURPOSE: To obtain the titled polymer having high stereoregularity, by using a highly active catalyst prepared by reacting a specific Mg compound with a Ti compound and an alcohol, treating the reaction product thus obtained through a specific method, and incorporating the resultant product with an organoaluminum compound.
CONSTITUTION: A magnesium compound expressed by formula I (R1 is 1W10C alkyl or cycloalkyl; X1 is halogen; n is 1.0W2.0) is catalytically reacted with a titanium compound expressed by formula II (R2 is 1W10C alkyl or cycloalkyl; X2 is halogen; m is 0W3.0) and an alcohol expressed by the formula R3OH (R3 is 1W10C alkyl, etc.) in the absence or presence of an organic acid ester, e.g. ethyl benzoate, in the first stage. The component (A) thus obtained is then treated with an organic acid ester and then combined with (B) an organoaluminum compound in the second stage to give a polymerization catalyst, which is used to polymerize an α-olefin, e.g. propylene.
