Abstract
PURPOSE: To prepare an ethylenic high polymer having a large average particle size and a small amount of a catalyst residue, by copolymerizing ethylene and an α- olefin in the presence of a catalyst consisting of a specific composite solid catalyst component and an organoaluminum compound.
CONSTITUTION: Ethylene is copolymerized with an α-olefin in the presence of a catalyst system comprising A) a composite solid catalyst component obtained by polymerizing ethylene or copolymerizing it with a 3W8C α-olefin in a hydrocarbon solvent in the presence of a catalyst consisting of (a) a solid component prepared by reacting (a1) magnesium alcoholate (solid reaction product) with (a2) a tetrafunctional Ti compound and (b) an organoaluminum compound shown by the formula I (R13 is 20≥C hydrocarbon; X3 is halogen; n is 2W3) and B) an organoaluminum compound shown by the formula II, III, or IV (R14W16 are H, halogen, 8≥C alkyl, or alkoxy; R17W20 are 8≥C alkyl; R21 is halogen, 8≥C alkyl; X4 is halogen).
