The invention discloses a halogen-free flame retardant antistatic polycarbonate composition and a preparation method thereof. The composition comprises the components based on parts by weight: 50-70 parts of polycarbonate, 5-20 parts of polymer which can form a third phase, 8-15 parts of impact modifier, 3-15 parts of phosphonium flame retardant, 0.2 part of fluoro-polyolefine additive, 1-10 parts of conducting material and 0.1-1 part of other accessory ingredient. When in operation, the polymer which can form the third phase, the phosphonium flame retardant, the conducting material and other accessory ingredient are firstly melted and extruded by a double screw extruder to prepare intermediate composition; after being melted and extruded by the double screw extruder, the intermediate composition, the polycarbonate, the impact modifier and the fluoro-polyolefine additive are pelleted and then dried. The composition prepared by the invention does not contain chlorine and bromine, has excellent antistatic property, flame retardance, impact resistance and formability and needs a little conductive filler.

Treatment compositions in the shape of a strip or patch include a substantially solid adhesive layer and a treatment gel. A barrier layer may be included on an outer surface of the adhesive layer to form a treatment strip. The adhesive layer comprises a substantially solid adhesive composition that has increased adhesiveness to oral tissue when moistened with saliva or water. The adhesive layer is formed from an intermediate composition that is heated to drive off the solvent. Using a treatment gel separate from the adhesive layer improves the potency and stability of an active agent that is sensitive to heat, as the treatment gel is typically not heated prior to use like the adhesive layer. The adhesiveness of the treatment composition or strip facilitates placement over a person's teeth. The moistened adhesive composition reliably adheres the treatment composition or strip against a user's teeth during a desired procedure. Because a substantial portion of the adhesive composition remains solid or semi-solid during treatment, the adhesive composition maintains a substantial portion of its adhesive properties and internal cohesive strength compared to, e.g., a treatment gel used by itself.

The disclosure relates to using metallic acrylate compounds such as zinc diacrylate (ZDA), zinc dimethacrylate (ZDMA), among others for curing epoxy functional (and other cross-linking compounds), and to compositions containing such compounds for use in powder coat, film, adhesive, among other applications.

Dental bleaching compositions in the shape of a dental tray, strip or patch include an adhesive activation composition and a dental bleaching gel. A barrier layer may be included to form a dental bleaching device that protects the bleaching composition from saliva or moisture during use. The adhesive activation composition is substantially solid and has increased adhesiveness to oral tissue when moistened with saliva or water. The adhesive activation composition is formed from an intermediate composition that is heated to drive off the solvent. Using a bleaching gel separate from the adhesive activation composition improves the potency and stability of the bleaching agent prior to use. During use, saliva or moisture cause the bleaching gel to be activated as the bleaching agent activator in the activation composition is leached therefrom so as to react with and destabilize the bleaching agent within the bleaching gel.

Methods for producing a protein extract from cells, such as cells containing viral proteins, are provided.

For example, a semiconductor device is formed using a molybdenum oxide material containing molybdenum trioxide (MoO₃) as its main component and MoO_y (2<y<3) at 4% or more.

Dental bleaching compositions in the shape of a dental tray or tray-like form include a substantially solid adhesive layer and a dental bleaching gel. A barrier layer may be included on an outer surface of the adhesive layer to form a dental bleaching device. The adhesive layer comprises a substantially solid adhesive composition that has increased adhesiveness to oral tissue when moistened with saliva or water. The adhesive layer is formed from an intermediate composition that is heated to drive off the solvent. Using a bleaching gel separate from the adhesive layer improves the potency and stability of the bleaching agent, as the bleaching gel is not heated like the adhesive layer. The shape of the dental bleaching device facilitates placement of the device over a person's teeth with substantially less manipulation compared to the use of initially flat bleaching strips. The moistened adhesive composition reliably adheres the dental bleaching composition or device against a user's teeth during a bleaching procedure. Because a substantial portion of the adhesive composition remains solid or semi-solid during bleaching, the adhesive composition maintains a substantial portion of its adhesive properties and internal cohesive strength compared to, e.g., a bleaching gel used by itself.

Provided is a method for producing a laminate, having excellent production stability, and with which it is possible to obtain a display device with good anti-glare properties, while suppressing the occurrence of glare at an extremely high level, and having excellent contrast. Provided is a method for producing a laminate comprising an anti-glare layer having surface irregularities, on one surface of a light-transmitting substrate.
