摘要:
The invention relates to mixtures containing (a) an oligomeric compound, containing repeating units of the general formula (I) or the acid addition salts thereof, and/or (b) a compound of the general formula (II) or the acid addition salts thereof, and (c) at least one compound of the general formula (III), and (d) optionally further additives, as well as to the use of these mixtures for stabilizing inanimate organic materials against the action of light, oxygen and/or heat. Furthermore, the invention relates to inanimate organic materials, containing at least one of these mixtures and objects produced therefrom. Furthermore, the invention relates to methods for stabilizing inanimate organic materials against the action of light, oxygen and/or heat.
摘要:
The present invention includes polymer interlayers that are used in multiple layer glazing panels. Interlayers of the present invention comprise a thermoplastic polymer, a plasticizer, a tungsten oxide agent, and a stabilizing agent that prevents the degradation of the tungsten oxide agent. Interlayers incorporating such components have improved ultraviolet light blocking character, and also maintain optical quality over time.

摘要:
A nanocomposite particle comprises a core particle being one organic molecule or an assembly of organic molecules; and a shell layer enclosing the core particle and comprising organic titanosilicate which comprises an Si and Ti oxide containing a bond expressed by M-O-M, where M is Si or Ti, and has an organic group bonded to at least part of silicon atoms. Because of being enclosed by the shell layer, the organic molecule is shielded from substances causing degradation of the organic molecule. Therefore, when the organic molecule contains an ultraviolet absorbing molecule or a pigment molecule, its ultraviolet absorbing effect or its coloring property is maintained for a long time. Besides, since the shell layer comprises organic titanosilicate, the nanocomposite particle is excellent in dispersibility, for example, in a coating composition including resin vanish.
