    摘要： 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.

    摘要： A cross-linked polyethylene insulated cable which is prepared by extrusion coating a polyethylene composition on a conductor, the polyethylene composition comprising polyethylene, more than 10% to less than 30% by weight of an ethylene-vinyl acetate copolymer having a vinyl acetate (hereinafter referred to as VA) content of about 28% to about 33% by weight, the EVA having an average particle diameter of less than 1.7 .mu.m (average of maximum 5 values), and an organic peroxide, and thereafter cross-linking the thus coated polyethylene composition.
