Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for producing an aqueous polymer dispersion, capable of dispersing a polymer having release properties as a dispersed material in water so that the polymer is dispersed as fine particles with good storage stability even when a small amount of an emulsifier is used, and to prepare the aqueous polymer dispersion prepared by the method. SOLUTION: The method for producing the aqueous polymer dispersion comprises emulsifying and dispersing a dispersion phase containing the polymer having the release properties in an aqueous dispersion medium containing the emulsifier, wherein a mixture of the dispersion phase and the aqueous dispersion medium is emulsified and dispersed by injecting the mixture with an injection pressure of >=6.5×10 Pa.
