摘要：A method for manufacturing coagulated particles from a latex prepared byemulsion polymerization has been eagerly demanded, which provides coagulatedparticles having a low content of fine powder and a low water content, and makespossible a granulating operation in the vicinity of the softening temperature of thepolymer. A method for manufacturing coagulated particles from a latex prepared byemulsion polymerization is provided which comprises step (A) of adjusting the

temperature of a latex prepared by emulsion polymerization within the range of Tm±15°C. wherein Tm represents the softening temperature of the polymer in the latex; step (B)of adding polyethylene oxide; step (C) of adding a coagulant to cause phase separationof a polymer component from an aqueous phase; step (D) of further adding a coagulantto form an aqueous suspension containing coagulated polymer particles having avolume-average particle size of 50 to 500 μm; and step (E) of adjusting the temperatureof the suspension to Tm or more.
