摘要： A flame-retardant thermoplastic elastomer composition is provided to produce a molded article possessing mechanical properties, flame retardancy and softness inherently possessed by a molted article obtained from a thermoplastic elastomer composition containing a mineral oil-based softening agent and a flame retardant and fails to stain a mold after injection molding. A production method includes step (1) obtaining a thermoplastic elastomer composition by dynamically crosslinking a polymer mixture (A) containing an ethylene-α-olefin-based copolymer rubber (A1) and a propylene-based polymer (A2) in the presence of a mineral oil-based softening agent (C) and a crosslinking agent (D), and step (2) kneading the thermoplastic elastomer composition, a halogen-free flame retardant (E), zinc oxide (F), and a thermoplastic resin with a polar group (G). The amounts of the components satisfy condition (p) when starting the dynamic crosslinking in step (1) and satisfy condition (q) when starting the kneading in step (2), respectively.

摘要： A method for producing a thermoplastic elastomer composition includes: (1) a step of dynamically vulcanizing 50 to 90% by weight of (A) an oil-extended ethylene-α-olefin-based copolymerized rubber and 10 to 50% by weight of (B) a propylene-based resin, where the total amount of the oil-extended ethylene-α-olefin-based copolymerized rubber (A) and the propylene-based resin (B) is taken as 100% by weight, in the presence of a crosslinking agent, thereby obtaining a thermoplastic elastomer, wherein the oil-extended ethylene-α-olefin-based copolymerized rubber (A) contains 100 parts by weight of an ethylene-α-olefin-based copolymer rubber having a Mooney viscosity (ML1+4100° C.) of 150 to 350 at 100° C. and 20 to 150 parts by weight of a mineral oil-based softening agent, and (2) a step of kneading 100 parts by weight of the thermoplastic elastomer and 15 to 120 parts by weight of (C) an ethylene-based copolymer containing unsaturated carboxylic acid units, thereby obtaining the thermoplastic elastomer composition.
