Abstract

PURPOSE: To obtain the titled high-quality copolymer having a narrow distribution of molecular weight with a high productivity, by using a novel catalyst containing a solid prepared from specific Mg compound, Ti compound, alcohol, organic halogenated organoaluminum compound and an organoaluminum compound.
CONSTITUTION: A halogenated organoaluminum compound expressed by the formula AlRl 1X1 3-l (R1 is hydrocarbon; X1 is halogen; 1≤l≤2) is added to a uni form hydrocarbon solution containing a magnesium compound expressed by the formula Mg(OR2)mX2 2-m (R2 is hydrocarbon; X2 is halogen; m is 1 or 2), a titanium compound expressed by the formula Ti(OR3)nX3 4-n (R3 is hydrocarbon; X3 is halogen; n is an integer 1, 2 or 3) and an alcohol expressed by the formula R4OH (R4 is hydrocarbon) to give a solid insoluble in hydrocarbons. The resultant solid is then combined with an organoaluminum compound to give a catalyst system. Ethylene is then copolymerized with an α-olefin in a hydrocarbon in the presence of the resultant catalyst system under such conditions as to dissolve the formed polymer.
