A method comprising: providing a powder composition including at least one ultrafine, spherical thermoplastic polymer powder having a glass transition temperature (Tg) of at least 150 degrees C.; and powder bed fusing the powder composition to form a three-dimensional article.

Powder bed fusing thermoplastic polymers

Described herein is a composite comprising a matrix comprising a polymeric material; and at least one sized fiber selected from the group consisting of polyetherimide-sized fibers, epoxy-sized fibers, and combinations thereof.

Polyetherimide-fiber composites

Disclosed are compositions comprising: (i) 5-45 wt. % of an acrylonitrile-styrene-acrylate (ASA) graft copolymer or acrylate-modified ASA, (ii) 2-82 wt. % of at least one polyestercarbonate which is a block polyestercarbonate comprising organic carbonate blocks alternating with arylate blocks, said arylate blocks comprising ester structural units derived from at least one 1,3-dihydroxybenzene moiety and at least one aromatic dicarboxylic acid, and having a degree of polymerization of at least about 4; and (iii) 5-60 wt. % of at least one rigid thermoplastic polymer comprising structural units derived from styrene and acrylonitrile; alpha-methylstyrene and acrylonitrile; alpha-methylstyrene, styrene, and acrylonitrile; styrene, acrylonitrile, and methyl methacrylate; alpha-methyl styrene, acrylonitrile, and methyl methacrylate; or alpha-methylstyrene, styrene, acrylonitrile, and methyl methacrylate, or mixtures thereof, wherein wt. % values are based on the weight of components (i)-(iii) and wherein a molded article made from the composition has a notched Izod impact strength of at least 5 kilojoules per square meter (kJ/m) as determined according to ISO 180 at room temperature and a Vicat B value of at least 101&#xb0; C. determined at 120&#xb0; C. according to ISO 306. Articles made from said compositions are also disclosed.
