Abstract: An article of manufacture comprising a polyester composition, the article comprising, as measured by differential scanning calorimetry with a heating rate of 20 C per minute on first heating according to ASTM D3418, at least two different crystalline melting temperatures, wherein a first crystalline melting temperature and a second crystalline melting temperature are each independently 200-290 C; and a first heat of fusion and a second heat of fusion that are each independently at least 3 J/g, preferably wherein a ratio of the first heat of fusion to the second heat of fusion is 1:5-5:1, wherein the polyester composition comprises a first polyester having a phosphorous content of greater than or equal to 20 ppm, a second polyester, and 5-50 weight percent of a plurality of fibers, based on the total weight of the polyester composition, wherein the plurality of fibers have a diameter of 5-25 micrometers.

Abstract: A polyetherimide composition includes specific amounts of a polyetherimide, a block polyestercarbonate, a block poly-carbonate-polysiloxane, and a core-shell impact modifier in which the core includes a polysiloxane and the shell includes a poly(alkyl (meth)acrylate). Relative to a corresponding composition lacking the core-shell impact modifier, the polyetherimide composition exhibits increased impact strength while substantially retaining flame retardancy. Also described are associated articles, including articles formed by additive manufacturing, and a method of additive manufacturing.
