    摘要: A thermoplastic acrylic resin is provided. The thermoplastic acrylic resin is a graft copolymer in which a stem polymer is an acrylic resin containing acrylonitrile and another ethylenically unsaturated monomer, and a branch polymer is a polymer composed of an ethylenically unsaturated monomer. The acrylonitrile is contained in an amount of 35 mass % or more and 84.5 mass % or less, the other ethylenically unsaturated monomer is contained in an amount of 15 mass % or more and 64.5 mass % or less, and the polymer composed of an ethylenically unsaturated monomer is contained in an amount of 0.5 mass % or more and 40 mass % or less. Thus, provided are a thermoplastic acrylic resin having improved melt-processability without compromising heat resistance, a method for producing the thermoplastic acrylic resin, a thermoplastic acrylic resin composition, a molded body, an acrylic fiber, and a method for producing the acrylic fiber.

    摘要: Provided is a composition for a non-aqueous secondary battery functional layer capable of forming a functional layer that can provide a battery member such as an electrode or a separator with both excellent blocking resistance and excellent process adhesiveness. The composition for a functional layer contains a particulate polymer A. The particulate polymer A has a core-shell structure including a core portion and a shell portion that at least partially covers an outer surface of the core portion. The core portion is formed from a polymer having a glass-transition temperature of higher than 25° C. and lower than 80° C. The shell portion is formed from a polymer having a glass-transition temperature of −80° C. to 25° C. The proportion constituted by the core portion among the total of the core portion and the shell portion is 30 mass % to 80 mass %.

    摘要: A super absorbent thermochromic resin and a preparation method thereof are disclosed. The resin comprises the following components by weight percent: 30-60% of a monomer, 0.01-0.5% of an initiator, 0.01-4% of a dispersant, 0.01-5% of a cross-linking agent, 0-20% of a diluent, 0.5-2% of an auxiliary, 0.1-10% of a thermochromic pigment, and the balance of water. Compared with the prior art, the super absorbent thermochromic resin prepared by the present invention can effectively indicate the temperature changes of the resin in a drying state and a water absorption state through color changes. The reaction finishes in 6-10 min, with a simple process, smooth polymerization, short reaction time and high productivity. The super absorbent thermochromic resin has a good stability and can be widely applied to the medical industry and daily use articles industry.

    摘要: A thermally expandable microcapsule, which shows excellent heat resistance and a high expansion ratio and thereby can be suitably used for molding processes involving high shearing force, such as kneading molding, calender molding, extrusion molding, and injection molding. The thermally expandable microcapsule also provides a foamed product using the thermally expandable microcapsule. The thermally expandable microcapsule contains a shell made of a polymer; and a volatile expansion agent as a core agent encapsulated in the shell, the storage elastic modulus (E′) of the shell at a temperature of 200° C. and a frequency of 10 Hz being 1×105 N/m2 or more, the storage elastic modulus (E′) of the shell at a temperature of 250° C. and a frequency of 10 Hz being 1×105 N/m2 or more, and a maximum displacement amount measured by thermomechanical analysis being 300 μm or more.
