Abstract The present invention relates to a method for producing a dry powder of a graft polymer, which comprises the steps of: coagulating graft polymer latex to produce graft polymer slurry; storing the graft polymer slurry at a temperature of 90.0 to 97.0℃; and transferring the stored graft polymer slurry to a dehydration device and dehydrating the graft polymer slurry while introducing a washing solvent having a temperature of 90.0 to 95.0℃ to produce a wet powder of the graft polymer. 본 발명은 그라프트 중합체 라텍스를 응집하여 그라프트 중합체 슬러리를 제조하는 단계; 상기 그라프트 중합체 슬러리를 90.0 내지 97.0 ℃에서 보관하는 단계; 및 보관된 그라프트 중합체 슬러리를 탈수 장치로 이송하고, 온도가 90.0 내지 95.0 ℃인 세척 용매를 투입하면서 탈수하여 그라프트 중합체 습윤 분말을 제조하는 단계를 포함하는 그라프트 중합체 건조 분말의 제조방법에 관한 것이다.
