| 摘要 |
<p>The present invention relates to electrically conductive devices comprising at least one electrically conductive substrate surrounded by a foamed 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 one 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 2 to 20 carbon atoms. Such devices include, for example, wire and cable assemblies.</p> |
