摘要： The present invention relates to a solid catalyst (D) for olefin polymerization comprising a magnesium-containing solid component (A) carrying thereon an organoaluminum-oxy compound (B) and a metallocene compound (C), the magnesium-containing compound (A) being obtained by heat treating a magnesium compound represented by the general formula: MgX2.nH2O where X represents a halogen atom and n is an integer of 1 to 12, and to a method of producing an olefinic polymer using the catalyst. In the case where the above solid catalyst for olefin polymerization is used, catalyst activity, particularly activity per solid catalyst, is high. Therefore, a deashing treatment step such as catalyst removal can be omitted. Further, the olefinic polymer produced has a narrow molecular weight distribution, and in the case of a copolymer, its monomer composition is uniform.
