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: An expandable thermoplastic resin particle including a polymer obtained by a process including polymerizing monomers including 60 to 80 parts by weight of α-methylstyrene and 40 to 20 parts by weight of acrylonitrile. A content of residual monomeric components in the expandable thermoplastic resin particle is not more than 0.5% by weight. When an expanded mold article is produced from the expandable thermoplastic resin particle at an expansion ratio of 10 times, foam cells in a cross section of the expanded mold article have an average chord length of from 20 μm to 60 μm.

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 %.
