    摘要: A method of producing a low-odor emulsion includes: charging an aqueous polymer emulsion into a treatment vessel and supplying pressurized water vapor into the vessel through a supply passage, while maintaining the inside of the vessel in a state where water is boiled by bringing temperature of the aqueous polymer emulsion into a range of 50-90° C. and pressure in the vessel into 12 KPa to 57 KPa; and discharging water vapor in a gas phase part in the vessel and a volatile organic compound volatilized from the aqueous polymer emulsion to outside of a system. A ratio of an inner diameter of the vessel to an opening diameter of a supply opening for supplying the pressurized water vapor from the supply passage into the vessel is from 30 to 3000 for the inner diameter of the vessel relative to 1 for the opening diameter of the supply opening.
