Abstract: The invention relates to fluoropolymer filament for use in 3-D printing, and 3-D printed fluoropolymer articles having low warpage, excellent chemical resistance, excellent water resistance, flame resistance, and good mechanical integrity. Additionally, the articles of the invention have good shelf life without the need for special packaging. In particular, the invention relates to filament, 3-D printed polyvinylidene fluoride (PVDF) articles, and in particular material extrusion 3-D printing. The articles may be formed from PVDF homopolymers, copolymers, such as KYNAR® resins from Arkema, as well as polymer blends with appropriately defined low shear melt viscosity. The PVDF may optionally be a filled PVDF formulation. The physical properties of the 3-D printed articles can be maximized and warpage minimized by optimizing processing parameters.

Abstract: The invention relates to a porous separation article having a fluoropolymer, polyamide, PEEK, or PEKK binder interconnecting one or more types of interactive powdery materials or fibers. The interconnectivity is such that the binder connects the powdery materials or fibers in discrete spots rather than as a complete coating, allowing the materials or fibers to be in direct contact with, and interact with a fluid. The resulting article is a formed multicomponent, interconnected web, with porosity. The separation article is useful in water purification, as well as in the separation of dissolved or suspended materials in both aqueous and non-aqueous systems in industrial uses. The separation article can function at ambient temperature, as well as at elevated temperatures.

Abstract: The present disclosure relates to a single shell open interstage reactor (“SSOI”). The SSOI comprises a first reaction stage, an interstage heat exchanger, an open interstage region, and a second reaction stage. The SSOI may be configured for upflow or downflow operation. Further, the open interstage region of the SSOI may comprise a supplemental oxidant feed. When the open interstage region comprises a supplemental oxidant feed, the SSOI may further comprise a supplemental oxidant mixing assembly. Processes for producing acrylic acid through the oxidation of propylene are also disclosed.

Abstract: The viscosity of aqueous dispersions of normally solid organic peroxides may be advantageously lowered through the use of surfactants which are polyglyceryl esters of C6-C12 fatty acids. The reduction in viscosity facilitates milling the peroxides to reduce particle size and also provides dispersions of small particle size peroxides which may be readily poured or pumped.

Abstract: An organic peroxide formulation includes at least one organic peroxide and at least one cellulose compound. Embodiments of the organic peroxide formulations significant improvements in surface tackiness (often including but not limited to tack-free surfaces) when curing elastomers in the presence of oxygen. Embodiments of the present invention relate to organic peroxide formulations that can cure solid elastomers in the full or partial presence of oxygen using, for example, a hot air oven or tunnel, molten salt bath, or steam autoclave. Embodiments of the invention also relate to crosslinkable elastomer compositions, processes for curing the elastomers, and products made by such processes.

Abstract: A process for forming voided latex particles is improved by combining swelling and polymerization of an outer shell into a single step. The process includes contacting multi-stage emulsion polymer particles comprising a core, at least one intermediate shell, with a swelling agent, and polymerizing an outer shell after said contacting with swelling agent wherein the core and the at least one intermediate shell are contacted with swelling agent in the presence of less than 0.5% monomer based on the weight of the multi-stage emulsion polymer particles, and substantially all of the swelling occurs during polymerization of the outer shell.

Abstract: Disinfectant compositions include 0.001 to 10% by weight of hydrogen peroxide or a hydrogen peroxide source based on the total weight of the composition; 0.001 to 20% by weight of at least one amphoteric surfactant based on the total weight of the composition; and 0.001 to 15% by weight of at least one alkali metal or alkaline earth metal salt of a cyclic or heterocyclic aromatic compound comprising at least one hydroxyl group, carboxylic group, or combination thereof based on the total weight of the composition. The disinfectant compositions are particularly effective at treating surfaces contaminated with resistant bacteria, such as Staphylococcus aureus at a fast killing rate.
