Abstract
A process for the manufacture of enamels for wires for the electrical isolation of electrical conductors by reaction of polyesters of aromatic polycarboxylic acids with diamines at elevated temperature, characterized in that a polyester of trimellitic acid, containing free carboxyl groups, is reacted from trimellitic acid or trimellitic acid anhydride, ethylene glycol and cycloaliphatic diols with a diamine of the general formula ** (See formula) ** where Y is oxygen or a low molecular weight alcohol.
