Abstract
PURPOSE: To prepare an olefinic polymer having a high bulk density and almost free fine powder, by using a catalyst provided by adding an organoaluminum compound to the mixture obtained by prepolymerizing a cationically polymerizable monomer in the presence of a solid catalyst comprising a magnesium compound and a transition metal compound.
CONSTITUTION: Ethylene and/or an α-olefin are (co)polymerized in the presence of a catalyst system comprising (A) a solid component provided by prepolymerizing a cationically polymerizable monomer (e.g. styrene) in the presence of a solid catalyst component prepared by treating (a) a magnesium compond (e.g. anhydrous magnesium chloride) and (b) a compound containing one or more transition metals selected from titanium, vanadium, zirconium, etc. (e.g. titanium tetrachloride), wherein the weight average molecular weight of the resultant polymer is ≥800 and the amount of the polymer is 0.1W1,000wt% on the basis of the solid catalyst component, and (B) an organoaluminum compound.
