ABSTRACT:
N-Hydroxyalkyltrimellitic acid imides of high purity are prepared by reacting trimellitic acid anhydride with a monoalkanolamine in an aqueous medium comprising an amount of not less than about 0.025 liter of a certain specific solvent or solvent mixture per 1 mole of the trimellitic acid anhydride and can be advantageously used for production of their polymers having a high thermal stability and a good color tone.
