<p>A polyamideimide which has norbornane skeleton represented by general formula (I) is reacted, in a polar solvent, with a norbornane tricarboxylic acid anhydride represented by general formula (II), and a diisocyanate compound. Thus, the disclosed polyamideimide has a norbornane skeleton and exhibits excellent heat resistance and transparency. Also disclosed is a production method for the same. (In formula (I) X is a divalent organic group selected from among a divalent aliphatic group having 4-16 carbon atoms, a divalent alicyclic group having 4-16 carbon atoms and a divalent aromatic group.)</p> |
