PROBLEM TO BE SOLVED: To provide a manufacturing method of a polymer having controlled molecular weight distribution.SOLUTION: There is provided a method for controlling molecular weight distribution by controlling a relative monomer concentration during contacting with a precursor catalyst and/or using a catalyst containing a molecule having a catalyst amount of structure and represented by the following formula. M is 2 to 8 group metal as a neutral or charged part, Y is any substituent, L=pyridyl, pyridylamide or any connecting group, brake line=any bond, X is alkyl, aryl, H, anionic part or the like, R is alkyl, aryl, H or the like, y is atomic value of M, x is 1 to 6 and X and (CR)are a part of connection or ring.SELECTED DRAWING: None |
