Abstract
A process for selecting and extruding a copolymer having improved extrusion processability comprising (a) selecting one or more copolymers of ethylene and one or more alpha-olefins having 3 to 12 carbon atoms, each of said copolymers having essentially no long chain branching and having (1) a melt index selected from the range of about 0.1 to about 20 grams per 10 minutes, and (2) a melt flow ratio having at least about a value determined by the following formula: 2.7183 to the power of {(1.477 minus [0.279 times the natural logarithm of the selected melt index]) divided by 0.29} and (b) extruding said copolymer around an electrical conductor.
