Patent ID: 7235624

Claim:
A method for making an olefinic interpolymer composition having a low dissipation factor, said method comprising adding at least one charge dissipation modifier to an unmodified olefinic interpolymer composition, and wherein the unmodified 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 b) post-polymerization reactor residuals of at least one transition metal catalyst and a boron containing activator package; and wherein the at least one charge dissipation modifier is 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 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 iv) and mixtures thereof; and wherein the olefinic interpolymer composition has a dissipation factor which is at least 50% lower than the dissipation factor of the unmodified olefinic interpolymer composition.
