Patent ID: 7384994

Claim:
An olefinic interpolymer composition comprising the following: a) an olefinic interpolymer or a mixture of olefinic interpolymers, each comprising at least one C 2 -C 20 α-olefin monomer, and optionally comprising at least one polyene, and wherein at least one olefinic interpolymer further comprises at least one polyene; b) post-polymerization reactor residuals of at least one transition metal catalyst and a boron containing activator package, and wherein boron containing activator package comprises a fluorinated tri(hydrocarbyl) boron compound, including perfluorinated derivatives thereof, and having 1 to 10 carbon atoms in the hydrocarbyl or fluorinated hydrocarbyl group; and c) at least one charge dissipation modifier selected from the group consisting of: i) amine compounds of the general formula (I) and (II): wherein x is 3, and each R is independently selected from linear, branched and cyclic hydrocarbyl groups, or hydrogen, or together two or more R substituents are a cyclic hydrocarbyl group, and each R 1 to R 5 is independently selected from linear, branched and cyclic hydrocarbyl groups, or hydrogen, or, together, two or more of the R 1 to R 5 substituents are a cyclic hydrocarbyl group; ii) silica compounds; iii) phosphoric acid; and iv) and mixtures thereof; and wherein the composition has a dissipation factor which is at least about 50 percent lower than the dissipation factor of the same composition that has not been treated with the charge dissipation modifier.
