摘要:
A floor, wall or ceiling covering which comprises one or more substantially random interpolymers prepared by polymerizing one or more &agr;-olefin monomers with one or more vinylidene aromatic monomers and/or one or more hindered aliphatic or cycloaliphatic vinylidene monomers, and optionally with other polymerizable ethylenically unsaturated monomer(s). The floor, wall or ceiling covering has a good balance of properties, such as sufficient flexibility and conformability to uneven or contoured surfaces for efficient application to floors, walls, or ceilings, sufficient scratch resistance, sufficient indentation resistance, indentation recovery and/or sufficient abrasion resistance.

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.
