Olefin-Based Polymers, a Process for Making the Same, and a Medium Voltage Cable Sheath Comprising the Same

摘要

Olefm-based polymers containing boron and aluminum at a B:Al molar ratio of less than one are useful in the manufacture of medium and high voltage wire and cable sheath coverings. Such polymers exhibit good dielectric properties, e.g., a dissipation factor less than 0.05 radians as measured by ASTM D-150-98. The typical source of the boron and aluminum in these polymers are the cocatalysts used to make the polymers, i.e., cocatalysts containing boron and/or aluminum.
