A polymerization method of a high molecular compound (A1) having a structural unit (a0) derived from a compound represented by the following general formula (a0-1), selected from the group consisting of a cyclic ketone solvent, an ester solvent, and a lactone solvent Polymerization method of the high molecular compound (A1) characterized by superposing | polymerizing using the mixed solvent containing 10 mass% or more of 1 or more types of solvent. [In formula (a0-1), Ra < 1> is a monovalent substituent which has a polymeric group, La < 1> is an oxygen atom, a sulfur atom, or a methylene group, R < 1> is a C2-C20 linear or branched thing which may have a substituent. A linear hydrocarbon group or a cyclic hydrocarbon group which may have a hetero atom, n is an integer of 0 to 5] [Formula 1] |
