Abstract: A cable comprising one or more electrical conductors or a core of one or more electrical conductors, each conductor or core being surrounded by an insulating composition comprising a mixture of(i) about 20 to about 50 percent by weight of a homogeneous polyethylene having a polydispersity in the range of about 1.5 to about 3.5 and an essentially uniform comonomer distribution; and(ii) about 50 to about 80 percent by weight of a homopolymer of ethylene made by a high pressure process.

Abstract: An ethylene polymer having a Polydispersity Index of at least about 3.0, a melt index, MI, and a Relaxation Spectrum Index, RSI, such that (RSI)(MI.sup..alpha.) is greater than about 26 when .alpha. is about 0.7, and a Crystallizable Chain Length Distribution Index, L.sub.w /L.sub.n, less than about 3 is provided. Such ethylene polymer has processability equivalent or superior to even conventional high pressure polyethylene at similar melt index, yet need not be made under high pressure reaction conditions.
