    Abstract: A thermoplastic composition comprises a polymer blend. The polymer blend comprises a first polyimide and a second polyimide. The first polyimide has repeating units derived from a first dianhydride and a first diamine. The second polyimide has repeating units derived from a second dianhydride and a second diamine. Either the first dianhydride and the second dianhydride are the same or the first diamine and the second diamine are the same.

    Abstract: 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.
