摘要： A part material for printing three-dimensional parts with a selective deposition-based additive manufacturing system has a composition having a thermoplastic elastomer (TPE) polymer and a surface modifier. The TPE polymer is polyether block amide (PEBA). The part material is provided in a powder form having a D90/D50 particle size distribution and a D50/D10 particle size distribution each ranging from about 1.00 to about 2.0, wherein the part material is configured for use in the selective deposition-based additive manufacturing system having a layer transfusion assembly for printing the three-dimensional parts in a layer-by-layer manner.

摘要： Fine polymer particles are prepared by dissolving a polycarbonate, a poly(arylene ether), or a poly(arylene ether sulfone), each in a specific solvent, to form a slurry, heating the slurry to a temperature greater than the solvent boiling point to form a homogeneous solution, cooling the solution to form a dispersion of fine particles, and isolating the fine particles. A volume-based distribution of the isolated fine particles has a median equivalent spherical diameter less than or equal to 125 micrometers.

摘要： A method for manufacturing resin particles is provided. The method includes the steps of: dissolving a resin free of poly(lactic-co-glycolic acid) (PLGA) in a good solvent of the resin to prepare a resin solution; and discharging the resin solution from at least one discharge hole having an inner diameter of less than 1,000 μm into a poor solvent of the resin to form resin particles.

摘要： A method of preparing degradable and environment responsive composite microgels, belonging to polymer material synthesis and biomaterial technology fields. Firstly, a copolymer of L-malic acid and 6-hydroxyhexanoate is prepared; then, N,N,N′,N′-tetramethyl cystamine is prepared. The copolymer and N,N,N′,N′-tetramethyl cystamine are mixed in an organic solvent to form a mixed solution which is added into excess distilled water to produce composite microgels. The microgels have advantages of mild preparing conditions, fast reaction speed without catalysts, no impurity remained, and controllable degradation rate. The microgels can load anticancer drug doxorubicin hydrochloride, showing environment responsive controlled release due to introduction of carboxyl groups and disulfide bonds.

摘要： An object of the present invention is to provide an acrylic resin powder suitable for hot melt adhesives which dissolves in polyol components such as polyalkylene glycols faster than conventional ones, as well as a resin composition which can be produced with lower energy than conventional ones. The object is achieved by using an acrylic resin powder comprising: a copolymer which contains a methyl methacrylate unit, wherein a volume average particle size of a primary particle is 0.1 to 10 μm, a volume average particle size of a secondary particle is 20 to 80 μm, a weight average molecular weight is 10,000 to 500,000, and the acrylic resin powder is soluble in polypropylene glycol having a weight average molecular weight of 1000 under stirring at a concentration of 10% by mass at 60° C. for 60 minutes.
