Electrical wire comprising an aromatic polyketone and polysiloxane/polyimide block copolymer composition

An electrical wire comprising a conductor and a covering disposed over the conductor wherein the covering comprises a thermoplastic composition and the thermoplastic composition comprises a polymer component, wherein the polymer component consists of a non-delaminated blend of

• an aromatic polyketone and
• a polysiloxane/polyimide block copolymer,
• wherein the polysiloxane/polyimide block copolymer has a siloxane content greater than or equal to 20 weight percent and less than 40 weight percent, based on the total weight of the block copolymer and the siloxane block comprises a unit of Formula (I)
• wherein
• R1-6 are independently at each occurrence selected from the group consisting of substituted or unsubstituted, saturated, unsaturated, or aromatic monocyclic groups having 5 to 30 carbon atoms, substituted or unsubstituted, saturated, unsaturated, or aromatic polycyclic groups having 5 to 30 carbon atoms, substituted or unsubstituted alkyl groups having 1 to 30 carbon atoms and substituted or unsubstituted alkenyl groups having 2 to 30 carbon atoms,
• V is a tetravalent linker selected from the group consisting of substituted or unsubstituted, saturated, unsaturated, or aromatic monocyclic and polycyclic groups having 5 to 50 carbon atoms, substituted or unsubstituted alkyl groups having 1 to 30 carbon atoms, substituted or unsubstituted alkenyl groups having 2 to 30 carbon atoms and combinations comprising at least one of the foregoing linkers,
• g equals 1 to 30, and
• d is 2 to 20 and
• wherein the thermoplastic composition has a limiting oxygen index of 30 to 60 as determined on 3.2 mm thick Izod bars according to ISO 4589.
