Electrical devices having polymeric members

Not Applicable The present invention relates to electrically conductive devices comprising at least one electrically conductive substrate surrounded by an interpolymer composition. The interpolymer composition comprises at least one substantially random interpolymer comprising:(i) polymer units derived from:(a) at least one vinyl or vinylidene aromatic monomer, or(b) at least one hindered aliphatic or cycloaliphatic vinyl or vinylidene monomer; or(c) a combination of at least on vinyl or vinylidene aromatic monomer and at least one hindered aliphatic or cycloaliphatic vinyl or vinylidene monomer; and(ii) polymer units derived from at least one aliphatic olefin monomer having from about 2 to about 20 carbon atoms. Such devices include, for example, wire and cable assemblies.
