Abstract:
An electrically conductive device comprising:(a) at least one electrically conductive substrate; and (b) at least one interpolymer layer wherein the interpolymer layer comprises a composition comprising 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 about 2 to about 20 carbon atoms, the interpolymer having from about 5 to about 40 mole percent aromatic monomer content and a log 10 (Endurance Time in Seconds) greater than or equal to {8.56[8.00âˆ’log10 (Applied Field Stress in V/m)]+4.7}, in the Applied Field Stress range of log10 (Applied Field Stress in V/m) is greater than or equal to 8.00, but less than or equal to 8.25.
