    摘要: A thermoplastic composition comprises a polysiloxane/polyimide block copolymer and a polyester/polyether block copolymer. The polysiloxane/polyimide block copolymer has 5 to 50 weight percent (wt %) polysiloxane, based on the total weight of the polysiloxane/polyimide block copolymer. The polyester/polyether block copolymer has 5 to 30 wt % polyether based on the total weight of the polyester/polyether block copolymer. In some embodiments the polysiloxane/polyimide block copolymer is present in an amount of 75 to 99 wt % and the polyester/polyether block copolymer is present in an amount of 1 to 25 wt %, with the weight percent of the block copolymers based on the combined weight of the two block copolymers.
