    Abstract: The invention relates to high efficiency diffusion lighting coverings useful in LED lighting applications. The diffusing lighting coverings are made of organic diffusing particles homogeneously dispersed in a transparent polymer matrix. The primary organic diffusing particles are refractive index mis-matched to the matrix polymer. The refractive index contrast between the polymer matrix and diffusion particles, and particle size are selected to provide a high efficiency (minimized particle loading). The high efficiency diffusion coverings provides excellent light diffusion, high hiding properties and high light transmission. The secondary diffusion particles may optionally be added to further improve selected target properties of the covering. Nano-sized ZnO inorganic particles may also function as diffusion particles and optical brighteners as well UV stabilizers. Articles made of this translucent composition are useful in commercial and residential lighting, motor vehicle illumination (lights, panels), street lighting, displays and signs, desktop monitors, and LCD/LED TVs.

    Abstract: The invention relates to an acrylic copolymer composition, wherein said copolymer comprises one or more (meth)acrylic monomer units and hydrophilic 2-carboxyethyl acrylate (CEA) and/or (meth)acrylic acid (MAA or AA) hydrophilic monomer units. The copolymer may be an amphiphilic terpolymer further including hydrophobic monomer units, such as tert-butyl cyclohexyl (meth)acrylate, isobornyl methyl acrylate (IBOMA) and isobornyl acrylate (IBOA). The copolymers are designed to meet the requirements of high heat resistance, improved bonding adhesion, and exhibit excellent mechanical properties, along with excellent chemical resistance. The copolymers of the invention possess a high Tg along with sufficiently high molecular weight for applications in battery cathode binders, coatings, composites, glass-/carbon-fiber re-enforced composites, water filtration membranes, optical lenses, extruded films, laminates, and (co-)extruded sheets/profiles.
