摘要： The invention relates to an aqueous fluoropolymer hybrid composition having superior weathering resistance while maintaining excellent mechanical properties in coatings, paints, caulks and adhesives. The composition is comprised of: a) a vinylidene fluoride polymer, such as KYNAR® polymers from Arkema, b) a first vinyl polymer immiscible with the vinylidene fluoride polymer and having a Tg of less than 0° C., and c) a second vinyl polymer of a different composition, also having a Tg of less than 0° C., and containing groups capable of crosslinking. The invention also relates to waterborne coatings or paints containing the aqueous fluoropolymer hybrid composition, and an article, object, or structure coated with the fluoropolymer hybrid composition on at least one surface, either in a factory or in the field, to confer protection and decorative properties. Free films made from the waterborne compositions of the invention have a dynamic mechanical analysis loss tangent, tan (δ), of greater than 0.22 at a temperature of 0° C.

摘要： A composition including a polymeric binder for the negative electrode of a secondary energy storage device is provided. The polymeric binder provides a matrix for particulate electrode-forming materials, which may include an active material and a conductive material. The polymeric binder contains acid functional groups. The polymeric binder also contains other functional monomers, which also may contribute to the performance of the polymeric binder in the negative electrode.

摘要： Shell-and-tube devices typically require regular maintenance. Described herein is an automated method for tracking the status of individual tubes during maintenance activities and recording status data for review and analysis. Status data may optionally be reported in real-time summary format and/or used to predict time-to-completion. The method helps to reduce the expense of performing maintenance activities in shell-and-tube devices, including shell-and-tube reactors and heat exchangers.

摘要： The invention relates to the use of a compatible thermoplastic material (film, sheet, or raft) as the base sheet or layer for 3-D printing an article. The use of the base film provides a means of printing a large article, and of reducing warpage by printing directly on the film. The printed article adheres to the film better than to traditional printer surfaces (glass, metal, glue, or reusable films), because the printed article and film weld together by forming chain entanglements, due to being compatible, miscible, or semi-miscible in the melt.

摘要： This process for synthesizing thiopolymers involves feeding elemental sulfur or sulfides and unsaturated hydrocarbons into an extruder. The extruder is comprised of a screw and a barrel. The screw is rotated so as to pressurize, heat and mix the sulfur or sulfides and unsaturated hydrocarbon to induce inverse vulcanization thereby producing thiopolymers such as polymeric polysulfides. The invented process can be accomplished by using sulfur which becomes molten at the conditions in the extruder or is preheated and unsaturated hydrocarbons as the starting material. The materials are fed through one or more extruders so as to induce mixing and reaction of the materials forming polysulfides.

摘要： 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.
