    Abstract: Process for the manufacture of polyester imides. Melamine, an at least tribasic carboxylic acid, a polyhydric alcohol and, optionally, an aromatic dicarboxylic acid are condensed at elevated temperature. The polyester imides are suitable, in the form of solutions, aqueous dispersions or melts, for use as baking enamels for metallic conductors.

    Abstract: Finely divided aqs. polyesterimided dispn. contains 20-60 wt. % polyesterimide with a particle dia. of 5 mum., 0.5-8 wt. % flow-promoting agent and -8 wt. % catalyst, the polyesterimide being a precondensate of (A) melamine, (B) >=1 di or poly-basic acid and/or its anhydride, acid chloride or ester of a lower mono-alkanol, (C) >=1 polyvalent alcohol and opt. (D) >=1 aromatic dicarboxylic acid or their esters with lower alkanols, the molar ratio of (A):(B) being from 1:1. 1 to 1:3. Prep. the precondensate contains (condensed) 5-15 wt. % (A), 15-70 wt. % (B), 15-25 wt. % (C) and 5-55 wt. % (D). The dispersion exhibits excellent storage stability and is suitable for prodn. of coatings, impregnations and adhesives bonds with improved heat stability, hardness and solvent stability.
