Abstract (en)
[origin: WO9924504A1] A water tree retarding additive and a composition for an electric cable comprising it are disclosed. The additive has general formula (I) where n = 1-3, m = 0-3, R1 = -H, -CH3, -(CH2)nCOOH, R2 = (a) a linear or branched, saturated C4-C20 alkyl, (b) a linear or branched, unsaturated C4-C20 alkyl, (c) a linear or branched, saturated C4-C20 acyl, if m=0, (d) a linear or branched, unsatured C4-C20 acyl, if m=0, (e) an aromatic group, (e) in formula (II) where R3 = (a)-(d), and m = 1-3. The additive preferably is N-lauroyl ethylenediamine-N,N',N'-triacetic acid.
