<p>Disclosed is a production method for a polyamideimide which has a nadimide skeleton. In the production method, a dicarboxylic acid which has a nadimide skeleton represented by general formula (I) (wherein, in the formula R1 is a divalent organic group selected from among an aliphatic group, an alicyclic group and an aromatic group) and a diisocyanate compound represented by general formal (II) are reacted. OCN-R2-NCO (II) (wherein, in the formula R2 is a divalent organic group selected from among an aliphatic group, an alicyclic group and an aromatic group). Thus, the disclosed novel production method provides a polyamideimide which has a nadimide skeleton and which exhibits excellent heat resistance and transparency.</p> |
