  • Patent number: 7384994
    Abstract: Olefinic interpolymer compositions comprising the olefinic interpolymer, residuals from a transition metal catalyst and boron containing activator package, and a charge dissipation modifier and methods for making them. The compositions have dissipation factors that are at least 50% less than the corresponding olefinic interpolymer compositions which have not been treated with charge dissipation modifiers. The compositions are useful in wire and cable applications.
