Zusammenfassung:	To provide a method for manufacturing resin pellets with high uniformity in size.SOLUTION: There is provided a method for manufacturing resin pellets, comprising: a polymerization step of polymerizing a monomer to form a thermoplastic resin; and a devolatilization treatment and extrusion step of performing devolatilization treatment of a volatile component containing the unreacted monomer from a polymer obtained in the polymerization step, and extruding a resin composition containing the thermoplastic resin. The method is characterized in that: the resin pellets are formed under substantially the same conditions using two or more lines, and a mixing step of mixing the resin pellets formed in the two or more lines is provided.SELECTED DRAWING: None 【課題】本発明は、サイズの均一性が高い樹脂ペレットを製造する方法を提供することを目的とする。【解決手段】単量体を重合させて熱可塑性樹脂を形成する重合工程と、前記重合工程により得た重合物から未反応の前記単量体を含む揮発性成分を脱揮するとともに、前記熱可塑性樹脂を含む樹脂組成物を押出成形する脱揮及び押出工程とを含む、樹脂ペレットの形成を実質的に同一の条件において２系列以上で行い、前記２系列以上で形成した樹脂ペレットを混合する混合工程を含む、樹脂ペレットの製造方法。【選択図】なし
