Abstract

PURPOSE: To obtain the titled polymer in high yield without requiring ash removing process, by using a catalyst comprising a component obtained by treating a reaction product of a specific Mg compound and an oxygen-containing Ti compound with an organic acid ester, followed by reacting the reaction product with a halogen-containing Ti compound and an organic Al component.
CONSTITUTION: (A) A magnesium compound shown by the formula Mg(OR1)n X2-n 1 (R1 is 1W10C alkyl, aryl, etc.; X1 is halogen atom; n is 1W2) is reacted by contact with an oxygen-containing titanium compound shown by formula Ti(OR2)4 (R2 is 1W10C alkyl. aryl, etc.) in the presence or absence of an organic acid ester, and the reaction product, directly or after being pretreated with an organic acid ester, is reacted with a halogen-containing tetravalent titanium compound shown by the formula Ti(OR3)mX4-m 3 (R3 is 1W10C alkyl or aryl, etc.) in the presence of the organic acid ester to give a solid component. An α-olefin is polymerized using a catalyst consisting of the solid component and (B) an organic aluminum compound.
