Abstract
A composition for an electric cable is described. The composition is characterized in that it comprises an ethylene plastic and a compound of the general formula (I) ##STR1## where n.gtoreq.1, PA0 R.sup.1, R.sup.2 and R.sup.3, which are the same or different, designate hydrogen or the residue of a carboxylic acid with 8-24 carbon atoms, with the proviso that there are at least two free OH groups and at least one residue of a carboxylic acid with 8-24 carbon atoms in the molecule. Preferably, n=3-12 and R.sup.1, R.sup.2 and R.sup.3 designate hydrogen or stearoyl and the compound of formula (I) is present in an amount of 0.05-2% by weight of the composition. The compound of formula (I) may be combined with other additives, such as polyethylene glycols. The composition may be used as an insulating layer or a semiconductive layer in an electric cable.
