Abstract: Provided are: an additive composition capable of imparting excellent mechanical properties to a molded article; a resin composition containing the same; a method of producing the resin composition; and a molded article. The additive composition contains: (A) a nucleating agent; (B) a hydroxy group-containing fatty acid lithium salt; and (C) a hydrotalcite. In this additive composition, the (A) nucleating agent contains an organic oxoacid metal salt, the content of the (B) hydroxy group-containing fatty acid lithium salt is 25 to 400 parts by mass with respect to 100 parts by mass of the (A) nucleating agent, and the content of the (C) hydrotalcite is 25 to 400 parts by mass with respect to 100 parts by mass of the (A) nucleating agent.

Abstract: A method for producing a resin composition of the present invention is a method for producing a resin composition, the method including a step of obtaining a resin composition by heating and melt-kneading a mixture containing a particulate nucleating agent in which D50 is equal to or more than 0.1 μm and equal to or less than 300 μm and a thermoplastic resin using a twin screw extruder (100) including, inside a cylinder (10), a screw (50) having kneading discs (60), in which the step of obtaining a resin composition includes an extrusion step of extruding the mixture supplied into the twin screw extruder (100) in an ejection direction under kneading conditions in which X and Y satisfy 4.0≤X in a range of 6.0×103≤Y≤7.0×104 when a volume-based ejection amount is denoted by X (10−6·kg·h−1·mm−3), and a strain rate is denoted by Y (min−1).
