ABSTRACT:
Carboxylic acids of the general formula I ##STR1## where R.sup.1, R.sup.2 and R.sup.3 independently of one another are each hydrogen, hydroxyl, carboxyl or C.sub.1 -C.sub.6 -alkyl and x, y and z independently of one another are each 0 or an integer of from 1 to 6, and/or their anhydrides can permanently suppress the formation of water trees in electrical medium and high voltage cables which contain electrically insulating and/or electrically semiconductive layers based on ethylene homopolymers and/or copolymers, even when the relevant layers contain water-soluble basic salts. Accordingly, polymeric mixtures based on ethylene homopolymers and/or copolymers which contain the above-mentioned carboxylic acids I and/or their anhydrides are very useful for the production of electrically insulating and electrically semiconductive layers as used in electrical medium and high voltage cables.
