Aliphatic-aromatic polyamidimides containing polyamides

A thermoplastic injection-moldable composition comprising 10 to 99.8%, by weight of the composition, of a polyamidimide condensation product, prepared at a temperature of from 0.degree. to 400.degree. C., from a mixture consisting essentially of a diisocyanate, a polycarboxylic acid anhydride and a lactam or a first polyamide, where the diisocyanate is a diisocyanate derived from isophorone;

• toluene diisocyanate;
• m-phenylenediisocyanate;
• 4,4'-diisocyanatodiphenylmethane;
• 4,4'-diisocyanatodiphenylether;
• naphthylene-1,5-diisocyanate;
• p-phenylenediisocyanate;
• 4,4'-diisocyanato-diphenyl-dimethylmethane;
• 4,4'-diisocyanatodicyclohexylmethane;
• an aliphatic diisocyanate containing two to twelve carbon atoms or mixtures thereof and 0.2 to 90%, by weight of the composition, of a second polyamide.
