Abstract
PURPOSE: To increase the yield of a polyolefin by using a catalyst system comprising an organometallic compound and a solid component prepared by pulverizing the reaction product of magnesium oxide with aluminum trichloride, together with an organic carboxylic acid, etc. and a titanium compound, etc.
CONSTITUTION: An olefin is (co)polymerized in the presence of a catalyst system comprising (A) a solid component prepared by pulverizing (a) a product of the thermal reaction of magnesium oxide with aluminum trichloride, together with (b) an organic carboxylic acid RCOOH, an organic carboxylic acid metal salt RCOOMe, an ester RCOOR', a ketone ROR', an alcohol ROH, an ether R-O-R' and/or a silicone, and (c) a titanium compound and/or a vanadium compound, and (B) an organometallic compound, e.g. organoaluminum compounds, etc. (R,R' are hydrocarbon; R'',R''' are H, alkyl, etc.; Me is IWIII group metal).
EFFECT: Elimination of the catalyst residue is unncessary, and the bulk density and the flow characteristics of the polymer are improved.
