Abstract
A composition comprises a ternary-phase polymer composite including components (A) ethylene/unsaturated ester copolymers having γρ of from <5 to >1 mN/m; at least two additional polymers selected from the group consisting of: (B) non-polar polymers having γρ of from >0 to <1 mN/m selected from the group consisting of polyethylene homopolymers, silane-functionalized polyethylene homopolymers, ethylene/alpha-olefin copolymers, and silane-functionalized ethylene/alpha-olefin copolymers, (C) ethylene/unsaturated ester copolymers having a γP of >5 mN/m, and (D) EPDM copolymers; and conductive filler dispersed in only one of (A) and the at least two additional polymers, wherein (i) one of the at least two additional polymers is selected from (B) and the other is selected from (C) or (D), or (ii) one of the at least two additional polymers is selected from (C) and the other is selected from (B) or (D).
