ABSTRACT:
Polyamide-imides are described which are derived by conventional procedures from 2,2-bis[4-(p-aminophenoxy)-phenyl]propane (or the corresponding diisocyanate) and trimellitic acid (preferably through the anhydride acid chloride). Copolyamide-imides derived from trimellitic acid, the above diamine (or diisocyanate) and certain other aromatic diamines or diisocyanates (4,4'-diaminodiphenyl ether, m-phenylene diamine and corresponding diisocyanates are preferred) are also described. The above polyamide-imides are engineering thermoplastics which, unlike closely related polyamides and polyimides, can be extruded and injection molded to form parts having good mechanical properties.
