Abstract
Disclosed herein is a process for producing an azo group-containing polymer comprising polycondensing a compound having an azo group in the main molecular chain and an alcoholic hydroxyl group, phenolic hydroxyl group, imino group or amino group at both ends thereof with a dicarboxylic acid chloride or a carbonate precursor except the polycondensation of a compound having an azo group in the main molecular chain and an alcoholic hydroxyl group at both ends thereof with a carbonate precursor.
