Abstract: Provided are: an additive composition which has an excellent extruder feed stability as a result of having an excellent powder flowability, and can impart excellent transparency and mechanical properties to molded articles; a polyolefin resin composition containing the additive composition; a method of producing a polyolefin resin composition; and a molded article of the polyolefin resin composition. The additive composition contains (A) 1-[8-propyl-2,6-bis(4-propylphenyl)tetrahydro[1,3]dioxino[5,4-d]-1,3-dioxin-4-yl]ethane-1,2-diol and (B) an aromatic phosphate metal salt represented by Formula (1) where R1 to R4 each independently represent an alkyl group having 1 to 6 carbon atoms; n represents a number of 1 or 2; when n is 1, M1 represents an alkali metal; and when n is 2, M1 represents hydroxyaluminum. In this additive composition, the mass ratio of (A) and (B), (A)/(B), is in a range of 10/90 to 90/10.

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).
