Treating With Organic Phosphorus-containing Material Patents (Class 521/41.5)
  • Patent number: 11034865
    Abstract: Provided is a barrier adhesive composition comprises polyisobutylene resin, organically modified nanoclay (e.g. montmorillonite or bentonite) and sorbent nanoparticles (e.g. CaO which acts as a desiccant and/or getter). In a preferred embodiment, the barrier adhesive composition is disposed on a gas-barrier film to form an adhesive barrier film. The adhesive barrier film can then be used for protection from oxygen and moisture in OLED displays and solid state lightings, solar cells, electrophoretic and electrochromic displays thin film batteries, quantum dot devices, sensors (e.g. touch sensor) and other organic electronic devices. The adhesive barrier film is especially well-suited for applications that require oxygen and moisture protection as well flexibility and good optical transmittance.

  • Patent number: 8710108
    Abstract: A proton conducting polymer electrolyte comprising a proton conducting ionomer cross-linked with an amount of a copolymer additive comprising cross-linking functional groups and other functional groups (e.g. proton carriers, chelating agents, radical scavengers) shows improved durability over the ionomer alone and provides for more stable inclusion of these other functional groups. The copolymer additive comprises at least two types of metal oxide monomers, one having cross-linking functional groups and the other having the other functional groups.

  • Patent number: 8153699
    Abstract: A surfacing composition made of recycled paint, which requires no priming, has a non-reflective “flat” appearance, and is partially composed of dried paint. The composition provides a useful application for used or excess household paint, which would otherwise require special methods of disposal and potentially create future toxic cleanup problems. The composition is made of granular dried paint and a water-based sealer, which can be spread on a surface to repair imperfections. The surface can then be finished, and no priming is required. Due to the composition's flat appearance, the patch does not display any characteristic sheen where the repair has been made. The composition provides a simple means of recycling paint, and provides a simple and inexpensive means of repairing imperfections in walls and other surfaces while saving the step of priming the patch before painting or repainting.

  • Patent number: 7547734
    Abstract: Recycled resin is produced by a method including a dismantling/recovery step of dismantling products containing resin moldings and recovering the resin moldings, a removal step of removing unwanted matter including metal components from the resin moldings, a sorting step of discriminating the materials of the resin moldings, and a crushing step of crushing the resin moldings. The method further includes, prior to the crushing step, detecting the metal components, and, after the crushing step, separating out and thus removing metal remaining in crushed material.

  • Patent number: 7425584
    Abstract: The present invention relates generally to the delulcanization of rubber. More specifically, the present invention relates to a process for the hydro-devulcanization of vulcanized rubber utilizing a rubber swelling solvent, a source of reactive hyrogen and elevated temperature and, optimally, also uses a dispersed molecular-scale hydrogenation catalyst that is introduced into the vulcanized rubber in a catalytically inert form that is soluable in the rubber swelling solvent.

  • Patent number: 7250451
    Abstract: A process for reclaiming sulfur-cured, vulcanized rubber by combining finely ground scrap vulcanized rubber within a specialized, twin-screw extruder capable of providing strong shearing and just-on-time mixing; adding a reclaiming agent to the extruder; and masticating the rubber scrap and reclaiming agent within the extruder until the rubber scrap is devulcanized. The present invention also discloses a unique composition of reclaiming agent, which preferably includes the following compounds: accelerators TBBS, ZMBT, MBT, and TMTM; activators zinc oxide and stearic acid; and zinc salts of fatty acids and sulfur. The reclaimed rubber is suitable for use in producing high-grade, rubber products without adding a binder, or for combining with fresh rubber compounds to produce high-specification rubber products.
