  • Publication number: 20210347981
    Abstract: An object of the present invention is to provide an impact modifier that provides impact resistance to a molded object obtained by molding a resin composition such as polycarbonate at a high temperature, and exhibits more excellent heat stability (preservation of mechanical properties after a wet heat test, discoloration, and flame retardance), and a thermoplastic resin composition including the impact modifier. The polyorganosiloxane-containing-rubber latex, in which a total amount of sulfate ions and sulfonate ions included in 100 g of the solid content is 2.4 mmol or less, a powder thereof, and a resin composition including the powder and a resin. Further, a molded object thereof and a production method therefor are provided.

  • Patent number: 10446850
    Abstract: A binder resin composition for secondary battery electrodes is described as containing a polymer (A) that has a structural unit represented by general formula (1) and a water-insoluble particulate polymer (B-1) and/or a water-soluble polymer (B-2) where (A), (B-1) and (B-2) are defined as described. A slurry for secondary battery electrodes contains the binder resin composition, an active material and a solvent. An electrode for secondary batteries is provided with a collector and an electrode layer that is arranged on the collector, where the electrode layer contains an active material and the binder resin composition. Alternatively, the electrode layer is obtained by applying the slurry for secondary battery electrodes to the collector, and drying the slurry thereon.

  • Patent number: 10361434
    Abstract: A binder resin for a nonaqueous secondary battery electrode of the invention satisfies Is?30 (Is indicates a sum of scattering intensities observed in a particle size range of from 1 to 100 nm) when a solution is formed by dissolving the binder resin in water at a concentration of 5% by mass and particle size distribution is measured by a dynamic light scattering method at 25° C. The binder resin contains a polymer (B) having a structural unit represented by the following Formula (11) and a specific structural unit. The binder resin also contains a polymer (?) having a specific structural unit and a structural unit represented by the following Formula (22), and/or a mixture of a polymer (?1) having a specific structural unit and a polymer (?2) having a structural unit represented by the following Formula (22).
