Abstract: A dispersant of an infrared absorbent dispersion is distributed in an outer layer of an infrared absorbent to form an independent unit dispersed in an organic solvent; the molecular structure of the dispersing agent has an active unit capable of undergoing a free radical copolymerization reaction with a methyl methacrylate monomer and/or a group capable of generating intermolecular forces with polymethyl methacrylate; and the organic solvent can be mutually soluble with the methyl methacrylate monomer and the polymethyl methacrylate. Due to the stable dispersion and suspension of the infrared absorbent in a dispersion and the high inter-miscibility and adaptability of the dispersion and the matrix material, the infrared absorbent is evenly dispersed in the organic glass. The infrared absorbent is tightly bound to the matrix via the dispersant on the outer layer, such that the organic glass is uniformly transparent under visible light and can uniformly block infrared light.

Abstract: A siloxane polymer contains a silsesquioxane unit and a linear siloxane unit in its main chain and has a cage-type silsesquioxane structure in its side chain. A highly transparent and flexible film having a small linear thermal expansion coefficient is produced by utilizing the cohesion force (physical crosslinking) of the cage-type silsesquioxane in the side chain. The siloxane polymer has repeating units respectively represented by formulae (1) and (4), and has terminal groups respectively represented by formulae (5L) and (5R) at its right and left terminals, wherein A represents a structure shown below.

Abstract: The present disclosure relates to a thermoplastic resin composition, a method of preparing the same, and a molded article including the same. For example, the present disclosure relates to a thermoplastic resin composition including 35 to 85% by weight of an alkyl acrylate-aromatic vinyl compound-vinyl cyanide compound graft copolymer (A) containing alkyl acrylate rubber having an average particle diameter of 50 to 120 nm and 15 to 65% by weight of a polymethacrylate resin (B). The thermoplastic resin composition has an alkyl acrylate coverage value (X) of 70% or more as calculated by Equation 1. The thermoplastic resin composition may have beneficial mechanical properties, such as impact strength, tensile strength, and flexural strength, surface hardness, transparency, and colorability and may be capable of preventing occurrence of whitening during bending due to beneficial non-whitening properties.

Abstract: Disclosed are hydrophobic, acrylic materials having both high refractive index and a high Abbe number. The materials may have an internal wetting agent, are well suited for use as implantable ophthalmic devices, and have a refractive index which may be edited through application of energy. When used for an intraocular lens, the high refractive index allows for a thin lens which compresses to allow a small incision size.
