Patent ID: 7144934

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