Patent ID: 8263722

Claim:
An electrical device comprising: (A) an electrical conductor, and (B) a polymeric insulating layer comprising: (i) from 50 to 100 wt %, by weight of the interpolymer and the terpolymer, of an ethylene interpolymer containing units derived from propylene, having: (a) a density of from 0.85 to 0.9 g/cm 3 , (b) an MI of from 0.01 to 2 g/10 min, and (c) an MIR (I 21 /I 2 ) of from 40 to 80, and wherein the ethylene interpolymer: (i) is obtained by solution polymerization using transition metal complex as a catalyst and a boron-containing non-coordinating anion, and (ii) has an undetectable level of NCA derived residue, as determined by boron content, as determined by ICP; (ii) from 0 to 50 wt %, by weight of the interpolymer and the terpolymer, of an ethylene-propylene-vinyl norbornene terpolymer; and (iii) a clay, flame retardant and/or an inorganic filler.
