    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.

    摘要: The invention relates to a moisture resistant composition comprising: a) from 20 to 80 weight percent based on the total weight of the composition of a polyetherimide copolymer made from a monomer mixture comprising 3,3′ bisphenol-A dianhydride (BPADA), and 4,4′-diaminodiphenyl sulfone (DDS); b) from 5 to 75 weight percent based on the total weight of the composition of polyetheretherketone (PEEK); and c) from 0 to 30 weight percent based on the total weight of the composition of a filler. The invention relates to a reflector substrate comprising a moisture resistant layer metalized with a reflective layer, wherein the moisture resistant layer comprising the moisture resistant composition. The invention relates to a method for producing a metalized coating without a primer comprising applying a reflective layer directly to a moisture resistant layer in the absence of a primer, wherein the moisture resistant layer comprises the moisture resistant composition.
