Abstract: A polymer produced by a polymerization process, in the gas or slurry phase, with a liquid carrier comprising an activator and a metal catalyst compound comprising a group 3 to 14 metal atom bound to at least one anionic leaving group and also bound to at least two group 15 atoms, at least one of which is also bound to a group 15 or 16 atom through another group which may be a C1 to C20 hydrocarbon group, a heteroatom containing group, silicon, germanium, tin, lead, phosphorus, or a halogen, wherein the group 15 or 16 atom may also be bound to nothing or a hydrogen, a group 14 atom containing group, a halogen, or a heteroatom containing group, and wherein each of the two group 15 atoms are also bound to a cyclic group and may optionally be bound to hydrogen, a halogen, a heteroatom or a hydrocarbyl group, or a heteroatom containing group.

Abstract: The invention relates to electric power cables, transmission lines or coaxial cables having at least one polymeric component. This polymeric component generally is a conducting, semiconducting, protective or insulating component. The electrical cables of this invention have improved resistance to water treeing and other improved properties. The polymer generally comprises ethylene polymerized with at least one C3 to C20 alpha-olefin and optionally at least one C3 to C20 polyene. The polymer utilized has a density in the range of about 0.86 g/cm3 to about 0.96 g/cm3, a melt index in the range of about 0.2 dg/min. to about 100 dg/min., a molecular weight distribution in the range of about 1.5 to about 30, and a composition distribution breadth index greater than about 45 percent.
