Abstract
1430004 Aromatic amino amides BADISCHE ANILIN- & SODA-FABRIK AG 20 June 1973 [21 June 1972] 29225/73 Heading C2C [Also in Divisions C3 D1 B2 and B5] The invention comprises compounds of Formulae 1 and 2 in which X is an oxygen or sulphur atom or a sulphonyl, carbonyl, imino, alkylene, arylene or cycloalkylene group and n is zero or 1 which may be prepared by reaction of an amine of Formula A where X and n are as defined above with isatoic anhydride in an inert solvent with elimination of CO 2 , and also compounds of Formulae 3 or 4 when prepared by the reaction of an amine of Formula 1 or 2 with trimellitic anhydride chloride in an inert polar solvent. The compounds of the invention may be reacted with an aromatic or endocyclic tetracarboxylic dianhydride to form a polyamido imide.
