Abstract:
A skin patch that can enhance the water resistance and handling easiness and can alleviate any irritation on the user. There is provided a skin patch having a flexible backing and, superimposed thereon, a plaster containing a styrene-isoprene-styrene block copolymer and having a glass transition temperature (Tg) of −45° to −35° C. and tan δ (lag angle) value, determined at dynamic viscoelasticity measurement (frequency 6.2832 rad/s) at 45° C., of 0.25 or less.
Abstract:
The mechanical properties of a polymer protective coating formed from an aqueous dispersion of a polymer having a low glass transition temperature are significantly improved by including in the dispersion solvent softened polymer nanoparticles made from a polymer having a high glass transition temperature.
Abstract:
The present invention relates to coating compositions containing a polymeric or copolymeric levelling agent, which has been prepared by nitroxyl-mediated polymerisation. Further aspects are a process for the preparation of smooth surface coatings and the use of said polymer or copolymer as levelling agent in coating compositions. Yet another aspect are specific ethylenically unsaturated monomer compositions from which copolymers can be obtained by atom transfer radical polymerisation or nitroxyl mediated polymerisation, which copolymers are useful as levelling agents in coating compositions. Still another aspect is the use of poly-tert.-butyl acrylate or poly-tert.butylmethacrylate as a levelling agent in powder coating compositions.
Abstract:
The present invention relates to a polymer article that includes electrically conductive fibers to provide electrical electromagnetic interference (EMI) shielding and their method of manufacture. The invention includes a method for forming shielding materials by impregnating conductive fibers in a polymer material via direct injection of the conductive fibers into the extrusion process. The invention also includes EMI shielding polymers and products that are radio-frequency and electromagnetically shielded by parts formed of the shielding polymer.
