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 Dis 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 () including, inside a cylinder (), a screw () having kneading discs (), in which the step of obtaining a resin composition includes an extrusion step of extruding the mixture supplied into the twin screw extruder () in an ejection direction under kneading conditions in which X and Y satisfy 4.0≤X in a range of 6.0×10≤Y≤7.0×10when a volume-based ejection amount is denoted by X (10·kg·h·mm), and a strain rate is denoted by Y (min).
