Abstract: Encapsulated peroxide particles inhibit skin inflammation. A method of encapsulating a solid peroxide comprises dispersing solid peroxide particles (e.g., benzoyl peroxide) in an aqueous dispersion of fatty acid salt to form a peroxide/fatty acid salt dispersion, wherein the peroxide particles have a mean particle size (D50) of 10 μm or less; and subsequently encapsulating the solid peroxide particles by reacting the one or more monovalent fatty acid salts with one or more multivalent salts of calcium, magnesium, aluminum, silver, and/or zinc, thereby forming encapsulated peroxide particles.

Abstract: A beeswax and/or beehive or bee keeping equipment surface is treated with a composition containing at least one solvent, at least one surfactant and at least one oxidizing agent (e.g., peroxide), optionally also containing other components such as an oxidizing agent activator, a viscosifying agent, an enzyme and/or a pH control agent, to reduce the amount of pesticide residues on the beeswax surface and/or disinfect against any bacterial, viruses, and fungi infestation.

Abstract: The use of compatible, semi-miscible or miscible polymer compositions as support structures for the 3D printing of objects, including those made from polyether-block-amide copolymers such as PEBAX® block copolymers from Arkema, polyamides such as RILSAN® polyamides from Arkema, polyether ketone ketone such as KEPSTAN® PEKK from Arkema, and fluoropolymers, such a KYNAR® PVDF from Arkema, especially objects of polyvinylidene fluoride and its copolymers. One particularly useful miscible polymer is an acrylic polymer, which is miscible with the fluoropolymer in the melt. The support structure composition provides the needed adhesion to the build plate and to the printed object and support strength during the 3D printing process, yet it is removable after the fluoropolymer object has cooled. The support polymer composition is selected to be stiff and low warping, yet flexible enough to be formed into filaments.

Abstract: Polymers containing halogen functionality are prepared by the addition or condensation polymerization of at least one halogenated reactant containing at least two active hydrogen-containing functional groups per molecule and at least one halogenated heteroalkyl or halogenated heteroalkenyl group per molecule and at least one co-reactant containing at least two functional groups reactive with the active hydrogen groups of the at least one halogenated reactant.

Abstract: A composite polymer process aid is provided. The process aid includes one or more inorganic mineral fillers and one or functionalized polymers. The functionalized polymers include at least one base polymer functionalized with an epoxy, hydroxyl, β-keto ester, β-keto amide, or carboxylic acid reactive functional group. The composite polymer process aid is in the form of a plurality of individual particles. At least a portion of the individual particles include both inorganic mineral fillers and the functionalized polymers. The composite polymer modifier is formed by a process of: i) blending an aqueous solution, an aqueous dispersion, an aqueous suspension, an aqueous slurry, or a dry powder of the mineral fillers with an aqueous solution, an aqueous dispersion, an aqueous suspension or an aqueous emulsion of the functionalized polymers to form an aqueous blend, and ii) powderizing the aqueous blend to form the composite polymer process aid.

Abstract: A coated separator for a lithium ion battery contains the porous separator substrate, and coatings on at least one side of the separator. The organic coating contains a silane functionalized fluoropolymer-acrylic composition or a mixture of silane functionalized fluoropolymer and non-silane functionalized fluoropolymer. The present invention can improve the adhesion of the coated separator to electrodes and offer good swelling properties in electrolyte.
