摘要： A method of manufacturing an article using a powder bed fusion technique including depositing a first layer of a dry blend mixture on to a target surface, the dry blend mixture comprising a thermoplastic polymer powder and a stearate additive in a range of 2,000 ppm to 20,000 ppm; directing energy to the first layer of the dry blend mixture so as to melt and sinter at least portion of the first layer of the dry blend mixture; and successively depositing layers of the dry blend mixture and directing energy to the deposited layers so as to melt and sinter at least a portion of the successive layers to a prior layer to perform a layer-by-layer process until a three-dimensional structure is obtained.

摘要： A process for treatment of nanoparticles of mineral filler for obtaining processed nanoparticles for use in polymerization in the presence of nanoparticles which includes the steps of (a) drying a mineral filler with an inert gas to remove catalyst poisons; (b) mixing the mineral filler dried obtained in step (a) with a swelling agent in a liquid state or near a critical state or in the supercritical state; (c) subjecting the swelling agent of the mixture obtained in step (b) to an endoenthalpic or isoentalphic phase change by altering the conditions of the temperature and/or pressure; (d) subjecting the nanoparticles of the mixture obtained in step (c) to contact of scavenging agent to react with catalyst poisons; then the mixture obtained in step (d) can be dried in a step (e) with an inert gas to remove sub-products from scavenging agent and catalyst poisons to obtain the treated nanoparticles.

摘要： Polymer compositions may comprise propylene, present in a range of 80 to 95 wt % of the polymer composition, and two comonomers selected from a group comprising ethylene and C4-C10 alpha olefins, wherein the polymer composition has a total content of the comonomers in the range of 5 to 20 wt % of the polymer composition. Cap liners may be formed from the polymer compositions. Caps may comprise a closure formed from polypropylene and a polypropylene-based cap liner that lines at least a portion of the closure.

摘要： A process of producing a composition comprising a copolymer of ethylene and one or more C4-C8 α-olefins, may include copolymerizing the ethylene and the one or more C4-C8 α-olefins in the presence of a procatalyst and an alkylaluminum cocatalyst. The procatalyst may be a Ti-containing Ziegler Natta procatalyst and the polymerization may include the procatalyst and the alkylaluminum cocatalyst in amounts such that a molar ratio of Al:Ti ranges from about 0.5 to about 50.0.

摘要： A method of obtaining ketones from a fermentation process may include collecting an off-gas and a fermented broth from a fermenter, transferring the off-gas from the fermenter to a ketone recuperation module and the fermented broth to a fluid separating module, and isolating the ketones from both the off-gas and the fermented broth. The off-gas and the fermented broth may both comprise a ketone.
