Aromatic polyketone and polysiloxane/polyimide block copolymer composition

A thermoplastic composition comprising a non-delaminated blend comprising a polymer component consisting of

• 1 to 90 weight percent of a polyarylether ketone;
• and
• 10 to 99 weight percent of a polysiloxane/polyimide block copolymer, wherein the polysiloxane/polyimide block copolymer has a siloxane content of greater than 0 and less than 40 weight percent based on the total weight of the block copolymer and the siloxane block comprises units 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, d is 2 to 20, and weight percent is based on the combined weight of the polyarylether ketone and the polysiloxane/polyimide block copolymer.

A thermoplastic composition comprising a non-delaminated blend comprising a polymer component consisting of

• 25 to 75 weight percent of a polyarylether ketone, based on the combined weight of the polyarylether ketone and a polysiloxane/polyimide block copolymer;
• and
• 25 to 75 weight percent of a polysiloxane/polyimide block copolymer, based on the combined weight of the polyarylether ketone and the 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 units 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, d is 2 to 20, and
• wherein the blend has a siloxane content, based on the combined weight of the polysiloxane/polyimide block copolymer and the polyarylether ketone, of 5 to 25 weight percent.
