Process for producing azo group-containing polymer having azo group in main chain
摘要:
A process for producing an azo group-containing polymer which comprises polycondensing:

(A) an azo-containing compound having an azo group in the main molecular chain and alcoholic hydroxyl, phenolic hydroxyl, imino or amino groups at both ends thereof, or a modified azo-containing compound which has been prepared by reacting a compound having an azo group in the main molecular chain and alcoholic hydroxyl groups at both ends thereof with a dicarboxylic acid chloride, with
(B) a carbonate precursor, or when (A) is the azo-containing compound, a dicarboxylic acid,
with the proviso that when the azo-containing compound is the compound having an azo group in the main molecular chain and alcoholic hydroxyl groups at both ends thereof (B) is not a carbonate precursor.
