ABSTRACT:
Polyamideimides are described which are derived by conventional procedures from particular 1,1-cycloaliphatic bis(phenylamine) compounds (or the corresponding diisocyanates) and trimellitic acid (preferably through the anhydride acid chloride). The polyamideimides are engineering thermoplastics characterized by the combined properties of solubility, melt processability, and resistance to thermal oxidation.
