A method for manufacturing a methacrylic resin molding material used for a massive molding material is provided to supply a methacrylic resin molding material having a high uniformity of an angle of repose. A method for manufacturing a methacrylic resin molding material used for a massive molding material comprises a step of attaching amide compounds to a surface of a methacrylic resin pellet at 35 °C or more. The amount of amide compounds is 0.003-0.05part by weight on a basis of 100part of the methacrylic resin pellet. The amide compounds are bis-amide compounds. A melting point of the amide compounds is in a range of 30-200 °C. The methacrylic resin pellet is obtained by cutting a stranded methacrylic resin. |
