METHOD FOR MANUFACTURING AN OLEFIN POLYMER

PROBLEM TO BE SOLVED: To provide a method for manufacturing an olefin polymer capable of controlling the polymer composition and excellent in terms of molding workability and mechanical strengths.SOLUTION: The provided method for manufacturing an olefin polymer satisfies the following requisites (1) and (2) simultaneously: (1) the weight ratio [W] through [W] (n is an integer of at least 2) of two or more types of solid catalysts (W) through (W) (n is an integer of at least 2) fed into the polymerization system is 0.05 or above and 0.95 or below (the sum of [W] through [W] is assumed to be 1.0); (2) the solid catalysts (X) through (X) are obtained by contacting at least two types of transition metal complexes (A) and (B) with solid carriers, and in a case where the respective solid catalysts (X) through (X) are used alone, the ratio of the maximal value [MFRα] and minimal value [MFR ] of the melt flow rate (MFR: 190°C, load: 2.16 kg) of a polymer obtained as a result of olefin polymerization under polymerization conditions identical to the polymerization conditions specific to the requisite (1) satisfies the following relational formula: 1
