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.
