Abstract: A process for the manufacture of finely divided polyester-imide powders wherein solutions of polyester-imides in organic solvents are solidified by cooling, the solvent is removed by sublimation and the solid product is pulverized. The powders may be used, as aqueous dispersions, to produce heat-resistant coatings on metallic conductors.

Abstract: Impregnating-, or laminating and adhesive agent based on polyesterimide precondensates, and opt. contg. polar organic solvents, comprises the reaction prod. of (A) melamine, (B) >=1 di or polybasic acid and/or its anhydride, acid chloride or ester of a lower mono-alkanol, (C) >=1 polyvalent alcohol and, opt. (D) >=1 aromatic dicarboxylic acids or their esters with lower alkanols, the molar relationship of (A):(B)being from 1:1.1 to 1:3. Pref. the precondensate contains (condensed) 5-15 wt.% (A), 15-70 wt.% (B), 10-25 wt.% (C) and 5-55 wt.% (D). The precondensates show esp. advantageous processing props. and impregnates, laminates and adhesive bonds made with the agent show excellent flexural strength and good temp. stability.

Abstract: Dicarbonyl chlorides (I) contg. imide gps. are produced by (a) suspending trimellitic anhydride (II) and aromatic diamines (III) of the formula H2N.C6H4.X.C6H4.NH2) (in which X is CH2, 0, S, SO2 or CO; the NH2 gps. can be in the o-, m- or p-position) in a high-boiling inert organic liquid (IV) and reacting to the diimido-dicarboxylic acid (V) and then (b) converting (V) to (I) with SOCL2 or COCL2. High temp. -resistant polymers and pigments are produced by reacting a suspension of (I) in PhNO2, without further purificn., with diphenols, diamines or aminophenols. (I) are obtd. in almost 100% yield and in high purity by a process suitable for technical operation.

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.
