Abstract:
The invention relates to a method for preventing the agglomeration in particular of rubber during gas-phase polymerization, by coating the surface of the polymer particles with an inert, particulate material. The method is characterized in that coating of the rubber particles with the inert, particulate material takes place outside the fluid-bed reactor.
Abstract:
Articles are provided, including a substrate having a first major surface, the substrate including a nonwoven material, a woven material, or a foam. The article further includes microcapsules having an outer surface and a plasticizer encapsulated in the microcapsules, where the plurality of microcapsules is attached to the first major surface of the substrate with a polymeric material. A method of making an article is also provided, including providing a substrate having a first major surface and providing microcapsules having an outer surface and a plasticizer encapsulated in the microcapsules. The method further includes attaching the microcapsules to the first major surface of the substrate with a polymeric material, thereby forming a polymeric matrix attached to the first major surface of the substrate.
Abstract:
High-melting antimicrobial polymer fibers and antimicrobial fabrics comprising such fibers are prepared by preparing a masterbatch of polymer pellets (e.g., PET), silver and copper salts, and a compounding agent which provides free flowing polymer pellets which can be prepared in advance, with a long shelf life. Polymer masterbatches prepared by the methods of the invention can produce limited color or off-white antimicrobial fibers and fabrics using conventional melt spinning manufacturing methods. Fabrics incorporating fibers of the present invention are potent inhibitors of Athlete's foot fungi, gram negative and gram positive bacteria, and drug resistant pathogens.
Abstract:
A method includes contact printing an active composition onto a surface of a release substrate to form a printed surface. The active composition spontaneously dewets the surface of the release substrate to form active deposits on the surface of the release substrate. The active composition comprises an active agent dissolved or dispersed in an aqueous liquid vehicle. A pressure-sensitive adhesive layer is disposed on the printed surface.
Abstract:
The present invention is directed to a fluoropolymer tape having an electrically conductive surface. More specifically, the present invention is directed to a polytetrafLuoroethylene (PTFE) tape and method for producing an electrically conductive tape by blending vapor-grown carbon fiber or carbon nanotubes or combinations of both with PTFE.

Abstract:
The present invention relates to the foams of the polyvinyl chloride nanocomposites comprising of polyvinyl chloride, layered inorganic compounds, and foaming agents. They are effective in that they have superior mechanical strength and non-flammability even with a low specific gravity; demonstrate a high foaming efficiency even with a small amount of a foaming agent; and have an even microcellular structure.
Abstract:
A conducting polymer-inorganic nanoparticle nanoarray is provided. Nanoparticles are formed and capped which provide enhanced properties to the nanoparticles and allow easier handling of them. The capping may be done when the nanoparticles are formed and may functionalize the nanoparticles. The nanoparticles are then bound to conducting polymers in order to produce an electrically conducting matrix which may in turn be electrically bound to a substrate to form an anode or cathode for a Lithium battery. In the matrix the nanoparticles are wired to each other electrically via the capping agent and/or the conducting polymer. The conducting polymer allows for repeated Li+ insertion in use as a battery anode or cathode.
