Electric wires or cables with styrene containing dielectric layer

Abstract

Electric wires or cables having a dielectric layer or layers of an uncross-linked or cross-linked mixture of (1) a polyolefin and (2a) polystyrene or (2b) a styrene copolymer. The polystyrene is present in such an amount as to provide a 10 to 30% styrene content, based on the entire mixture weight, while if the styrene copolymer is used it is present in such an amount as to provide a 3 to 30% styrene content, based on the entire mixture weight. The mixture may comprise, alternatively, both polystyrene and a styrene copolymer in an amount so as to provide a 10 to 30% and a 5 to 20% styrene content, due to the former and the later, respectively, based on the entire mixture weight.

Dependencies are inferred from the claim text.
