Abstract

PURPOSE: To prepare a modified ethylene polymer having large particle size, broad molecular weight distribution and improved moldability, by using a polymerization catalyst comprising a slurry of specific solid catalyst components prepared by reaction of a specific metal compound etc., an organoaluminum compound, a prepolymer, etc.
CONSTITUTION: Ethylene etc. are polymerized in the presence of a catalyst system comprising (I) a slurry obtained by mixing (A) the solid catalyst component prepared by contacting (a) the reaction product of a magnesium alcoholate with the product obtained by reacting an aluminum trihalide with a silicon-containing organic compound, with (b) a halogen-containing tetravalent titanium compound, with (B) the solid catalyst component prepared by reacting (c) a magnesium alcoholate with (d) a zirconium alcoholate and (e) a halogen-containing organoaluminum compound, in a hydrocarbon solvent, and (II) the catalyst consisting of (f) a composite solid catalyst component prepared by prepolymerization of ethylene etc. in the presence of an organoaluminum compound, and (g) an organoaluminum compound.
