    Abstract: A novel multi-functional linear siloxane compound, a siloxane polymer prepared from the siloxane compound, and a process for forming a dielectric film by using the siloxane polymer. The linear siloxane polymer has enhanced mechanical properties (e.g., modulus), superior thermal stability, a low carbon content and a low hygroscopicity and is prepared by the homopolymerization of the linear siloxane compound or the copolymerization of the linear siloxane compound with another monomer. A dielectric film can be produced by heat-curing a coating solution containing the siloxane polymer which is highly reactive. The siloxane polymer prepared from the siloxane compound not only has satisfactory mechanical properties, thermal stability and crack resistance, but also exhibits a low hygroscopicity and excellent compatibility with pore-forming materials, which leads to a low dielectric constant.

  • Patent number: 7732553
    Abstract: A process is provided for producing curable polyorganosiloxanes where noble metal oxides are used as hydrosilylation catalysts. The noble metals can be used in solid granular form or as part of a fixed bed, and do not form part of the final curable composition or cured product. The cured polyorganosiloxanes have increased stability and can be used as encapsulation resins at a temperature far lower than 300° C., have excellent light transmission properties (colorless transparency) in a wavelength region of from ultraviolet light to visible light, light resistance, heat resistance, resistance to moist heat and UV resistance, and do not generate cracks and peeling even in use over a long period of time.
