Abstract
Polyamide based coating powders having a practically uniform grain size distribution are prepared employing the precipitation procedure provided that the polyamide is dissolved in ethanol at 127 DEG to 135 DEG C. and that the solution is cooled while distilling the ethanol in such a manner that the reactor jacket temperature does not drop below the temperature of the reactor contents until the end of the precipitation stage.
