摘要： To provide a polymer compound production method which is capable of improving yield while lowering the dispersity of the molecular weight.
A method of producing a polymer compound A containing a constitutional unit (1-2) having a group obtained by removing one or more hydrogen atoms present on Ar 1 from a compound represented by the formula [1-2], comprising
a first step of separating high molecular weight components contained in a polymer compound B, by a fractionation precipitation method, from the polymer compound B containing a constitutional unit (1-1) having a group obtained by removing one or more hydrogen atoms present on Ar 1 from a compound represented by the formula [1-1], to obtain a polymer compound C composed of the high molecular weight components, and
a second step of converting the above-described constitutional unit (1-1) contained in the above-described polymer compound C obtained by the above-described first step into the above-described constitutional unit (1-2), to obtain the above-described polymer compound A:

[wherein, Ar 1 , R A and R B are as shown in the specification].
