The present invention relates to a method for producing a thermoplastic resin and, more particularly, to a method for producing a thermoplastic resin, which comprises a step of adding a water-soluble silicate compound and a metal salt coagulant to an α-methylstyrene-vinyl cyanide copolymer latex. The present invention has an effect of providing a method for producing a thermoplastic resin which is excellent in heat resistance by injecting an additive when agglomerating or curing an α-methylstyrene-vinyl cyanide copolymer latex, and controlling the injection timing thereof. |
